How to append something to an array?

Answer 1

You can use push and apply function to append two arrays.

var array1 = [11, 32, 75];
var array2 = [99, 67, 34];

Array.prototype.push.apply(array1, array2);
console.log(array1);

It will append array2 to array1. Now array1 contains [11, 32, 75, 99, 67, 34]. This code is much simpler than writing for loops to copy each and every items in the array.
