• What is AngularJS?

Angular JS is an open-source web application framework. It was originally developed in 2009 by Misko Hevery and Adam Abrons. It is now maintained by Google and by open-source communities to address any new updates and bugs. AngularJS is a framework for dynamic web applications that let the user use HTML as the template language (converts the static HTML to dynamic HTML). It uses data binding and dependency injections which stop a user from writing unnecessary code. AngularJS is mostly used for building web applications on MEAN stack which consists of MongoDB database, Express.js web server framework, Angular itself and Node.js server for providing runtime environment. 

Unlike other frameworks like React and Vue, Angular follows MVC (Model View Controller) architecture. This architecture consists of 3 major parts as Controller, View and Model. Angular is written in JavaScript as JavaScript is a browser-based language which makes Angular to deliver much rich, vibrant and fast-loading contents which increase the speed and performance of web applications. It has a list of different filters, directives, controllers, expressions and modules, in HTML that is added using the <script> tag with the source. It is also used for implementing client-side validations which decreases the load on the server side. Due to all its features, it is one of the most widely used frameworks for front-end development.

• Why is AngularJS?

Over the years, Angular framework has created a tremendous impact in eliminating unusable code and ensuring faster implementations. With its rapid evolution in the software industry from Angular JS (2010) to Angular 5(2017), it is one of the most widely used frameworks for front-end development. According to a survey in the year 2016 about 44.3 percent of software engineers are employed to work on AngularJS for UI creations. This massive impact in software industry is because of some of its key features which makes it unique:

1. Easy to use: Angular is a Javascript framework which supports DOM manipulation which makes it suitable for single-page applications. Over the years, the developers have also made it much easier to develop and test applications by introducing the MVC architecture
2. Support System: Angular is developed and assisted by Google every six month for its regular updates. Being an open-source framework, it has a huge collection of developers available globally in major platforms such as GitHub, Stack overflow etc.
3. Woks on client side: Angular is mostly used for front end development which allows a user to use it for client-side validations which also decrease the load on a server and makes the loading time faster.
4. Modularity: Angular manages its code into buckets, directives, pipes, components or services which makes the code more readable and allows the user to report bugs.
5. Filters: Angular directory offers the developers with different kinds of filters for alphabets, numbers, dates and much more, which in turn help a user to maintain a clean code so as to detect any error with much ease and efficiency.

4. Important tips for AngularJS

AngularJS is an amazing type of JavaScript framework which relies on a set of rules and best practices. It is very helpful in building a state-of-the-art AngularJS web application. The reason behind main AngularJS was to bring focus on the declarative programming style. It’s very easy to start but there are some complexities for which experienced developers also do not prefer to study it. So, here are some tips which would make it easy to study:

1. Many developers recommend to use LESS for web development with Angular JS as LESS is a CSS pre-processor and it also provides features like operators, mixins and functions.
2. We can take the advantage of one time binding if we are using an older version of AngularJS. 
3. Using chrome DevTools profiler and timeline, we can find the performance bottleneck which guides us to optimize our efforts.
4. Using Lodash, we can quickly rewrite our application’s logic to improve the built in Angular JS methods. It also enhances the application’s performance.
5. Online courses: There are variety of free courses available which you could choose for learning AngularJS
