Angular 2 – The WHATS & Why???

So now that I have to work using this wonderful technology, I have been trying to learn it.

Here’s my bit of understanding in a series the way I keep learning it…

What is Angular?

Angular is a leading framework for building JavaScript heavy applications and is often used in building single page applications or SPAs.

What is SPA?

In a standard web application, when we click a link, entire page is reloaded. In a SPA, instead of reloading the entire page, we replace the view that is in a content editor with another view.

It provides very fast and fluid experience.

Gmail is a fantastic example of SPA.

Why Angular 2?

There are multiple frameworks with the same offering, then why angular?

  • It is one of the leading frameworks that has been around for quite a few years now.
  • It is been re-written with the best practices for the future.
  • It has a huge community support backed by Google and is not going anytime soon.
  • The demand of angular development is increasing tremendously.

Note – Angular 2 is entirely new framework and has no dependency on Angular 1.x


Angular 2 is entirely written in Typescript

  • For any large JavaScript project, adopting Typescript results in a robust software.
  • It is a typed super set of JavaScript that compiles to plain JavaScript. You can say, any valid JavaScript is typescript.
  • It primarily provides optional static typing, classes, interfaces, modules, access modifiers, etc., basically like any other object oriented programming language.
  • The TS files get converted to JavaScript, hence, while deploying it is the JS files that run the application.
  • It is open source, and Integrated Development Environment (IDEs) are there to provide Intellisense and compile time checking. IDE could be Microsoft Visual Studio or Visual Studio Code.
