Benchmark: set.has vs. array.includes vs array.find vs map.has

Script Preparation code:

var a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var b = new Set(a)
var c = new Map();
a.forEach(x => c.set(x, x)) // just for test.

Tests:

Array.includes
return a.includes(9)
Set.has
return b.has(9)
Array.find
return a.find(x => x === 9)
Map.has
return c.has(9)
