Benchmark: concat vs [...spread]

Tests:

concat 100
const a = Array.from(new Array(100)) const b = Array.from(new Array(100)) const c = a.concat(b)
spread 100
const a = Array.from(new Array(100)) const b = Array.from(new Array(100)) const c = [...a, ...b]
concat 1000
const a = Array.from(new Array(1000)) const b = Array.from(new Array(1000)) const c = a.concat(b)
spread 1000
const a = Array.from(new Array(1000)) const b = Array.from(new Array(1000)) const c = [...a, ...b]
concat 10000
const a = Array.from(new Array(10000)) const b = Array.from(new Array(10000)) const c = a.concat(b)
spread 10000
const a = Array.from(new Array(10000)) const b = Array.from(new Array(10000)) const c = [...a, ...b]
