Benchmark: set.add vs array.push for massiver objects

Tests:

array.push
const massiveString = new Array(1048576).fill("s").join("") const myMassiveObject = new Array(1024).fill(1).reduce((p, v, i) => { p.i = massiveString; return p; }, {}); const a = [] for (let i = 0; i < 3000; i++) a.push({myMassiveObject, d: Date().now})
set.add
const massiveString = new Array(1048576).fill("s").join("") const myMassiveObject = new Array(1024).fill(1).reduce((p, v, i) => { p.i = massiveString; return p; }, {}); const s = new Set() for (let i = 0; i < 3000; i++) s.add({myMassiveObject, d: Date().now})
