AngularJS – What, Why, Advantages and Disadvantages
If you walk back in time, you will remember how we used to have static pages on the web. HTML was the perfect template language that will be used to declare such static documents. However, web applications have taken over now, and they are way more interactive & dynamic. AngularJS is a structural framework that can be of help in using Single Page HTML for declaring dynamic views in web-apps. Put differently, this is a framework that stretches HTML’s syntax in order to let your app’s components be expressed clearly and precisely.
There are a range of benefits of this structural framework that make it the tool of choice for modern-day web applications. It is designed by Google, and that happens to be one of its prime advantages. There’s a large community to help new as well as honed developers in getting over challenging obstacles in their projects. This also means that clients get exactly what they are looking for. Developers also love its dependency injection as well as data binding, as this ensures that a large part of the code that a programmer will write is now eliminated / automated. For the clients, this can translate into valuable time saving. The higher level of abstraction it offers to programmers also goes a long way in simplifying app development, and reducing development time.
In short, AngularJS is attracting young programmers to learn the language and clients to use this framework for their all-important web app projects.
