Benchmark: Array splice vs concat vs spread

Tests:

splice
var a = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var b = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var other = b.splice(0, 0, ...a);
concat
var a = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var b = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var other = b.concat(a);
spread
var a = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var b = [ "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello", "hello" ]; var other = [...a, ...b]
