JavaScript Date prototype properties

　JavaScript Date Object

prototypeProperties can add properties and methods to your Date() object.

Note:Prototype is a global property that is available for almost all objects (numbers, arrays, strings, dates, etc.).

Syntax:

Date.prototype.name = value

Create a new date method, which will set the month-numeric value to month conversion-name value:

Date.prototype.showMonth = function() {
var arr = ['Jan#39;,'Feb#39;,'Mar#39;,'Apr#39;,'May#39;,'Jun#39;,'Jul#39;,'Aug#39;,'Sep#39;,'Oct#39;,'Nov#39;,'Dec#39;];
return arr[this.getMonth()];
};

Then create a date and call the showMonth() method:

var d = new Date();
var month = d.showMonth();//　calling new method
