Benchmark: object assign vs object spread vs immutable-js vs immutability-helper on large data set 3

<script src="https://cdn.jsdelivr.net/npm/immutability-helper@2.7.0/index.min.js"></script>

Tests:

object spread
const obj = {}; for(i=0;i<100000;i++){ obj[i] = 'some long string which will need to be copied'; } const obj2 = {key: 'This is final object'} const final = {obj2, ...obj};
object assign
const obj = {}; for(i=0;i<100000;i++){ obj[i] = 'some long string which will need to be copied'; } const obj2 = {key: 'This is final object'} const final = Object.assign({}, obj2, obj) const r = final.key
immutable-js
const obj = {}; for(i=0;i<100000;i++){ obj[i] = 'some long string which will need to be copied'; } const immObj = Immutable.Map(); const obj2 = {key: 'This is final object'} const final = immObj.set(obj).set(obj2); const r = final.get("key")
