Extending Array.prototype in Node.js, from a require'd file

Question

I have the following saved in test.js. It successfully extends Array in the browser, but it doesn\'t seem to work with node and require. Can someone explain what\'s wrong

Answer 1

You can create a file which includes your extensions:

array.extensions.js

if(!Array.prototype.Last){
    Array.prototype.Last = function(){
        return this.slice(-1)[0];
    }
}

if(!Array.prototype.First){
    Array.prototype.First = function(){
        return this[0];
    }
}

then include this file to your startup file.

app.js:

require('{path}/array.extensions');
var express = require('express');
/* rest of your code */

referring this file once on startup is enough to use...
