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}; for(i=0;i<100000;i++){ final[i] = 'some long string which will need to be copied'; }
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(obj); const obj2 = {key: 'This is final object'} const final = immObj.merge(obj2); for(i=0;i<100000;i++){ final.set(i,'some long string which will need to be copied'); }
No copying
const obj = {key: 'This is final object'}; for(i=0;i<100000;i++){ obj[i] = 'some long string which will need to be copied'; } for(i=0;i<100000;i++){ obj[i] = 'some long string which will need to be copied'; }
