Fun Programming --JavaScript-- Why learn JavaScript?

Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript.

Atwood定律：凡是能用JavaScript写出来的，最终都会用JavaScript写出来。

There is always some prejudice against this JavaScript programming language, that it is not a strict programming language. But with jQuery, JSON, Node.js and HTML5, which are constantly being improved. It has also become a really powerful language. What we can do after learning JavaScript finish it?

1. web front-end development (dynamic web page will be used for all of JavaScript)
2. Game development (a variety of popular games)
3. Phone App (Android developers can combine HTML5 with the iOS App)
4. Database Interaction
5. Server interaction
6. Graphical interface processing

7. Animation effects

   So, have to say to learn JavaScript in large front-end is very important era.
