Benchmark: reduce.concat() VS concat(...spread) VS flat()

Tests:

reduce + Array.prototype.concat
var params = [[ 1, 2 ], [ "hello", true, 7 ]]; var other = params.reduce((acc, val) => acc.concat(val), []);
Array.prototype.flat
var params = [[1, 2, params], [ "hello", true, 7 ]]; var other = params.flat();
Array.prototype.concat with spread
var params = [[ 1, 2 ], [ "hello", true, 7 ]]; var other = Array.prototype.concat(...params);
