push.apply vs concat (v2)

Revision 2 of this benchmark created on

Setup

W = 100
iter = 20
function getArray(W) {
	return Array.from({length: W}, () => Math.floor(Math.random() * 100000))}

// Function using Array.push.apply()
function pushApplys() {
	arr1 = getArray(W);
	for (let i = 0; i < iter; ++i) {
		arr2 = getArray(W);
    	Array.prototype.push.apply(arr1, arr2);
	};
    return arr1;
}

// Function using Array.concat()
function concatArrays() {
	arr1 = getArray(W);
	for (let i; i < iter; ++i) {
		arr2 = getArray(W);
    	arr1 = arr1.concat(arr2);
	};
    return arr1;
}
