Benchmark: Array concat vs spread operator vs push v3

Tests:

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