Front-end development isn’t real development?
There is some sentiment out there that front-end development isn’t real development. It’s a swaggering, trollish sentiment. Still, it’s fun to puff our chests back sometimes. Let’s try to put a point on why front-end development is every bit as difficult and worthy of the title as any other subset.
The practice of front end development is similar to playing the bass: it’s easy to learn but difficult to master. There is a lot more to it than HTML and CSS
We have to deal with cross browser compatibility.
This was far and away the most cited gripe in the group. While Internet Explorer continues to be the brunt of most jokes, every browser has its own quirks that often require special development techniques to overcome.
It’s rather expected of us that we know how to build websites that can work cross-browser. We should know what browsers support what and how to debug and overcome browser-specific issues. We should know how to do emulate or otherwise test on a variety of browsers.
We should know tools that help us with cross-browser problems either automatically or enable us to write code to handle situations of support and nonsupport of features. We should know how to do fallbacks. We should know about progressive enhancement and graceful degradation.
Cross-browser compatibility is a hugely complex development task.
In addition to dealing with browser inconsistencies, front-end developers are also charged with developing for as many screen sizes, screen orientations, pixel densities, and input types as possible.
The burden of the massive landscape of different screens, browsers, and capabilities lies most heavily on front-end developers.
PYTHON AND AND ITS FRAMEWORK
Django is a free and open source web application framework written in Python. A framework is nothing more than a collection of modules that make development easier. They are grouped together, and allow you to create applications or websites from an existing source, instead of from scratch.
This is how websites – even simple ones designed by a single person – can still include advanced functionality like authentication support, management and admin panels, contact forms, comment boxes, file upload support, and more. In other words, if you were creating a website from scratch you would need to develop these components yourself. By using a framework instead, these components are already built, you just need to configure them properly to match your site.
The Official Project Site describes Django as “a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source.”
Django offers a big collection of modules which you can use in your own projects. Primarily, frameworks exist to save developers a lot of wasted time and headaches and Django is no different.
Django was created with front-end developers in mind. “Django’s template language is designed to feel comfortable and easy-to-learn to those used to working with HTML, like designers and front-end developers. But it is also flexible and highly extensible, allowing developers to augment the template language as needed.”
If you’re going to be working with Python, especially for web applications or web design, you’ll want to remember the Django framework. It will certainly come in handy.
CherryPy is another Python-based framework that is great to work with, although it is designed with the absolute minimalist in mind. It’s a framework you’ll want to explore after you already have some experience working with Python.

The popularity of Java script grows every day. It’s definitely the best scripting language which allows creating exciting interfaces and simplifies the development of web applications, being a perfect open source app development software and making the sites interactive and convenient to use.
The Javascript web development frameworks are issued and updated daily and that’s why it is difficult at times to go with the tides and understand which famework is most suitable and best matching for the project.
Before choosing a web app framework to apply the requirement and needs of the project to be taken into consideration.
The advantages of the frameworks
Javascript framework is a number of features and functions written in Javascript language and ready for the usage of the developers. These features simplify the interaction between the app and server and speed up the manipulating of the web page or app elements.
The main advantage of using a web application development frameworks is the fact that it provides immediate reaction to the user interacting with the site immediately.
The basic content of the traditional sites without frameworks is stored on the server and any new content , which is necessary to be upload requires reloading of pages. When frameworks are used , only the necessary blocks of a website are reloaded.
Some of the most advantageous benefits of the frameworks ‘usage:
- COST: The cost of the app development for websites decreases due to the JavaScript frameworks because they are free and open source code.
- Development speed: Java Script frameworks have good documentations. Some of the JavaScript frameworks are supported by such giant companies as Google etc. Due to such a lot of information, the speed of development increases.
- Efficiency: The usage of the pre-created functions and templates allows to carry out the projects more effectively. The developers have to write less code, which results in delivering projects meeting higher standards and more quickly.
Here are the top reasons to learn Python, if you are planning to start your career in Python.

Angular 9 is the most preferred framework for creating interactive components of a website. It was designed as a full-featured JavaScript framework to enhance simplicity and efficiency. Developers find AngularJS very effective especially in creating dynamic, single page apps, and supporting MVC (Model View Controller) programming structure. As the business environments become highly competitive, AngularJS has emerged as the super hero because of its intuitiveness and rich features.
The popularity of Angular 9:
Today, AngularJS is one of the frameworks that do not make the Model View Controller look skewed and together along with NodeJS, it simply works great with both the technology understanding same notations. Some frameworks simply bundle together the existing tools which make app development very difficult. However, AngularJS was carefully engineered to ensure that every tool works optimally and delivers great results.
After its release in 2009, AngularJS popularity has grown steadily and shows no sign of slowing down. But why is Angular becoming so popular and surpassing other frameworks? Here are a few samples of developers’ views after using the app.
Pros of Angular Apps:
When AngularJS 4 was released in March 2017, it made JavaScript to be named the best programming language of the year. The regular Angular updates have particularly made developers, and users get a special attachment to their apps because of enhanced security and features. Here are additional pros of Angularapps.
Time-saving: Projects that previously used to take many months with other frameworks can now be completed faster with AngularJS. All that AngularJS framework requires is splitting the app into several MVC components. From there, the framework takes over because you do not require additional coding.
The app is easy to learn and get started: Getting up and running with AngularJS is perhaps the simplest thing a developer can imagine. Simply include some attributes into the HTML, and you can complete the first app in a couple of minutes.
Data Binding in AngularJS is very easy: Can you remember trying to create a text property on a model that requires binding to your app UI? It is very difficult with most frameworks. That stress has been eliminated in AngularJS. In fact, you can see the ultimate results as you type in the span.
Affordability: Because AngularJS is an open source framework, developers can come up with custom apps at lower costs.
The main features of Angular 9:
The main reason that AngularJS has gained a lot of popularity is its unique features. The features make app development easy and result very intuitive. These features include;
Two-way data-binding: Data binding is one of the most notable AngularJS features. This feature helps save the developer from doing a lot of coding. In any app, 80% of the code base is dedicated to manipulating, traversing, and listening to DOM. However, data-binding in AngularJS helps to reduce the work so that the developer can concentrate with the app.
Ready to use templates: The AngularJS is simply plain HTML. The browser parses these templates into the DOM and transforms it to AngularJS compiler. Then, the AngularJS Framework traverses the templates to get rendering instructions called directives. The ready to use templates make it easy even for people with little computing skills come-up with great apps.
Dependency injection: This is an essential feature in AngularJS that makes the developer able to ask for dependencies as opposed to making them on his own. Think of this feature as a way of saying I need X and not starting to make X.
Testing feature: The AngularJS developer team worked with special focus on testability in mind. This means that you can easily test AngularJS apps.
AngularJS has started with version 1.0 and make so many positive changes when it comes to version 1.3 but there are some glitches regarding security in version 1 but when it comes with version 2.0 most of the problems are solved because in version 2.0 they have made so many good changes regarding security.AngularJS supports on fast and modern browsers such as chrome , Firefox , Opera , Internet Explorer 8 , Android , iOS6+ so we can work without any hesitation on AngularJS.
It’s one of the most popular JavaScript framework by which you can implement the things what JSP and another most of the technologies front frameworks implements.
Earlier days, the many frameworks were boom but When angular came into picture, it was a blast. As a developer I can surely say that in future any technologies having JavaScript as a base will not die. And recently AngularJS 2.0 is launched.
This framework gives a lot of things easy and it has number of features you can get it from it’s official website. And the funny thing is that if you know JavaScript and Jquery then there is no more efforts to learn the things.
The most awesome things you will love Two Way Data Binding and MVC Architecture.
Job opportunities hiring for Angular 9 Developers :
1. Major reason behind this is the trend of Startups in India and majorly startups are ready to use new frameworks and AngularJS & React both are among the most used UI frameworks.
2. With Google backing Angular, it has evolved as an excellent framework for UI development. One with proper functional knowledge of the framework can do wonders and make an application scalable, faster with very less effort.
3. 2-Way Data Binding, Templates, Routing, SPA. All these make AngularJS stand strong against other frameworks.
Moral of the Story: It is worthy. In market there is high demand for the AngularJS but the knowledgeable developers are less as compare to demand.

Ethical Hacking and what it is?
Ethical hacking , often performed by white hats or skilled computer experts, is the use of programming skills to determine vulnerabilities in computer systems. While the non-ethical hackeror black hat exploits these vulnerabilities for mischief, personal gain or other reasons, the ethical hacker evaluates them, points them out, and may suggest changes to systems that make them less likely to be penetrated by black hats. White hats can work in a variety of ways. Many companies utilize ethical hacking services from consultants or full-time employees to keep their systems and information as secure as possible.
The work of ethical hacking is still considered hacking because it uses knowledge of computer systems in an attempt to in some way penetrate them or crash them. This work is ethical because it is performed to increase the safety of the computer systems. It’s reasoned that if a white hat can somehow break the security protocols of a system, so can a black hat. Thus, the goal of ethical hacking is to determine how to break in or create mischief with the present programs running, but only at the request of the company that owns the system and specifically to prevent others from attacking it.
People enter the field of ethical hacking in a variety of ways. Many people are very computer savvy and many, but not all, have an educational background in computer science. In some instances, the white hat has gained his or her experience by first being a black hat.
If black hat hacking was at a sufficiently criminal level, the black hat turned white hat may have served jail time before resuming a career in a more productive and positive way as an ethical hacker. The computer world is peopled with former black hats, who now hold ethical hacking jobs. Conversely, some white hats, such as Steve Wozniak, never committed any illegal acts, but simply possess the know-how and skills to analyze problems with any computer system.
With increasing use of the Internet and concerns about its security, especially when it comes to things like consumer information or private medical details, there is considerable need for computer experts to work in ethical hacking. Even sites owned by organizations like the US government have been hacked in the past, and concern about information theft remains incredibly high. Designing impenetrable systems or identifying the current weaknesses of a system are vital parts of keeping the Internet safe and information private, and even with the present legion of ethical hackers that perform this work, there is still more work to do.
Those with interest in the field of ethical hacking often acquire a lot of their skills on their own, and many have particular talent with and affinity for computers. Some knowledge can also be acquired through formal education in computer programming. This work requires creativity, and the ethical hacker must be able to think outside of the box, coming up with as many possible ways as he or she can derive, a system might be encroached upon by black hats.

Angular is a JavaScript-based open-source front-end web application framework . AngularJS is a toolset for building the framework most suited to your application development. AngularJS was originally developed in 2009 by Miško Hevery as the software behind an online JSON storage service, that would have been priced by the megabyte, for easy-to-make applications for the enterprise. This venture was located at the web domain “GetAngular.com” and had a few subscribers, before the two decided to abandon the business idea and release Angular as an open-source library. It is fully extensible and works well with other libraries. Every feature can be modified or replaced to suit your unique development workflow and feature needs. HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop. Angular is a structural framework for dynamic web apps. With AngularJS, designers can use HTML as the template language and it allows for the extension of HTML’s syntax to convey the application’s components effortlessly. Angular makes much of the code you would otherwise have to write completely redundant.
Some reasons why developers should know “Angular ”:
Angular supports single page applications. Angular provides all of the necessary infrastructure from routing (being able to take a URL and map it to dynamically loaded pages), templates, to journaling (deep linking and allowing users to use the built-in browser controls to navigate even though the pages are not refreshing).
Angular helps developers Manage Stage. It’s the “illusion” of state that was perpetuated by ASP.NET that confuses developers when they shift to MVC. I once read on a rather popular forum a self-proclaimed architect declare that MVC was an inferior approach to web design because he had to “build his own state management.”
Angular gives developers control. Angular enables a new scenario known as a “directive” that allows to create new HTML elements and attributes. In my emulator, a directive to create two new tags: a “console” tag that writes the console messages and a “display” tag that uses SVG to render the pixels for the emulator (OK, by this time if you’ve checked it out I realize it’s more like a simulator) is used. This gives developers their controls – and more importantly, control over the controls.
Angular enables a Design- Development workflow. The designer can add markup without completely breaking an application because it depends on a certain id or structure to locate an element and perform tasks. Instead, rearranging portions of code is as easy as moving elements around and the corresponding code that does the binding and filtering moves with it. Although I haven’t yet seen a savvy environment where the developers share a “design contract” with the UI/UX team.
Angular handles dependencies. Dependency injection is something Angular does quite well. Single Page Applications use dynamic loading to present a very “native application” feel from a web-based app.
