get a value inside a function

Question

I am developing Node Js application using get-proxylist library so my question is how to get the value which is inside the function here is my code:

var proxylist = require('get-proxylist');
var array =[]
 proxylist(function(error, result){

        for(var i = 0; i < result.length; i++) {
            array.push(result[i]);
        }
    })
console.log(array[0]) // display undefined

You're dealing here with asynchronous operations. At the timeconsole.log(array[0]) is executed, the callback passed to proxylist is not yet executed and array is still empty.

Hey this is not connected to the question directly but can you recommend any good reads on asynchronous operations? – ZombieChowder Jan 15 '18 at 12:15
