Benchmark: Comparing array.concat.apply short form with empty array vs array.flat vs array.reduce

Script Preparation code:

var array1 = Array(400).fill().map(() => Math.round(Math.random() * 40));
var array2 = Array(400).fill().map(() => Math.round(Math.random() * 40));
var array3 = Array(400).fill().map(() => Math.round(Math.random() * 40));
var array4 = Array(400).fill().map(() => Math.round(Math.random() * 40));
var array5 = Array(400).fill().map(() => Math.round(Math.random() * 40));

var allArrays = [array1, array2, array3, array4, array5];

Tests:

array.apply
var others = [].concat.apply([], allArrays);
array.flat()
var others = allArrays.flat()
array.reduce
var others = allArrays.reduce(((combinedLength, label) => combinedLength + label.length), 0)
