So we have come to the last of my articles on object oriented JavaScript. You can read the last post by click ing here. This post will be about how JavaScript is proposed to change when (or if as the case may be) ECMAScript 4 (the spec that JavaScript is based on) is supported by the major browsers.

One of the changes that I am most happy about is the new proposed class structure. Yes JavaScript in the near future will be an object oriented language that is more in-line with languages like Java and C#.

Below is how the new structure is proposed.

Classes: A class describes an object by presenting those properties (fields) of the object that are always present (the
fixed properties or fixtures), including variables, constants, and methods16:

class C {
	var val // a variable property
	var large = Infinity // a variable property
	const x = 3.14 // a constant property
	function f(n) { return n+val*2 } // a method property
}

You would create instances of the class using the new method, just as you currently would with the current JavaScript object.

So, the answer to the question of should you use object oriented JavaScript is a resounding, Yes, especially with the direction that it looks like the language is going.
