One common misconception and practice among developers is the assumption that we can hop into the world of JavaScript and start writing useful code simply because we already know how to program in C,C++,Java or C#.
We learn how to declare variables using the var keyword, how to get handles to DOM elements with
document.getElementById("id") or getElementsByClassName("className") how to dynamically manipulate the styles attached to DOM elements and finally register event callbacks to be invoked for specific browser events.
The recent outburst of awesome JS libraries such as Angular JS, Backbone JS, Knockout JS, JQuery, D3 ect proves the power of the world's most used language, JavaScript. JavaScript is the engine that powers the web of today. It's the reason for the responsive web apps we enjoy today.
The power of JavaScript goes beyond mere DOM manipulations. It is a very powerful language when given the necessary respect. Though it was released prematurely by NetScape during the browser war era, JavaScript shipped with some really good stuffs. Despite the nasty side of JavaScript, it does more than simply manipulating DOM elements and handling of callbacks. The good sides of JavaScript is the reason why it was the best fit for developing Node JS, a server side JavaScript engine for implementing highly responsive, non-blocking and near realtime web apps.
JavaScript is an Object Oriented Programming language with constructs similar to classes, constructors and inheritance as we know from other mainstream OOP languages like C++, Java , C# etc.
For most of us, our learning of JS never comes to this street of OOP. JS is really cool when used from the good side.
To further build your understanding in JS, I recommend these books which I recently bought from leanpub
1. JavaScript, The Good Parts
2. Principles Of OOP in JavaScript
And finally to learn more client-side JS you can try
3. The Definitive Guide To JavaScript.
Isn't it time to say hi to JS?
May this year kick last year's ass!
