How to do this ? (Q & A)

In any condition,

I want to generate an Array easily

var array1 = [1, 2, 3, 4, 5];

var array2 = new Array(10);

But,

I want to generate an Array length with 100 and given random value ?

Here’s the magic solution I found.

Array.apply(null, { length: 100 }).map(function () {
    return Math.ceil(Math.random() * 100 + 1);
});

Done
