concat arrays

Benchmark created by V1 on

Description

There are different ways of adding concat arrays. You can use array.concat or leverage the Array.prototype methods.

So, what will be faster? Array.concat because, it's build for it.. Or a prototype function?

  var arr1 = [];
  var arr2 = [];
