Script Preparation code:
var nums50 = Array.from({length: 50}, () => Math.random() * 100 |0) var nums150 = Array.from({length: 150}, () => Math.random() * 100 |0) var nums500 = Array.from({length: 500}, () => Math.random() * 100 |0)
Tests:
slice and reverse 50
nums50.slice().reverse().forEach(n => n**2)
reduceRight 50
nums50.reduceRight((_,n) => n**2, null)
slice and reverse 150
nums150.slice().reverse().forEach(n => n**2)
reduceRight 150
nums150.reduceRight((_,n) => n**2, null)
slice and reverse 500
nums500.slice().reverse().forEach(n => n**2)
reduceRight 500
nums500.reduceRight((_,n) => n**2, null)
