Benchmark: concat vs spread funcking operator

Script Preparation code:

const a = [1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,0]
const b = ['a','b','c','d','e','f','g','h','i','a','a','a','a','a','a','a','a','a','a','a','a']

Tests:

concat
const a = [1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,0] const b = ['a','b','c','d','e','f','g','h','i','a','a','a','a','a','a','a','a','a','a','a','a'] const result = a.concat(b)
spread
const a = [1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,0] const b = ['a','b','c','d','e','f','g','h','i','a','a','a','a','a','a','a','a','a','a','a','a'] const result = [...a, ...b]
