Benchmark: set vs array mod - MeasureThat.net

Script Preparation code:

const b = []
for (let i = 0; i < 3000; i++) b.push(i)
const c = new Set(b);

Tests:

array.push
const a = [] for (let i = 0; i < 3000; i++) a.push(i)
set.add
const s = new Set() for (let i = 0; i < 3000; i++) s.add(i)
array.shift
for (let i = 0; i < 3000; i++) b.shift()
set.delete
for (let i = 0; i < 3000; i++) c.delete(i)
