Benchmark: Array concat vs spread operator vs push vs prototype.push.apply

Tests:

Array.prototype.concat
var params = [ "hello", true, 7 ]; var other = [ 1, 2 ].concat(params);
spread operator
var params = [ "hello", true, 7 ] var other = [ 1, 2, ...params ]
Push
var params = [ "hello", true, 7 ]; var other = [ 1, 2 ].push(...params);
Array.prototype.push.apply
var params = [ "hello", true, 7 ]; var other = Array.prototype.push.apply([ 1, 2 ],params);
