Javascript: Setting all array values to the same

Question

I want to make a new array (of X elements) with all the elements set to 0.
X is set before.
Anyone could make the most compact and easy code for that? Thank you for your help.

Answer 1

Just create a function:

function makeArray(size, defaultValue) {
    var arr = [];
    for (var i = 0; i < size; i++) arr.push(defaultValue);
    return arr;
}

var myArr = makeArray(10, 0);
