Benchmark: Object merging with spread operator

Script Preparation code:

function standard(oCol = {}) {
	return validate(oCol, 1, 2);
}        


function validate(oCol = {}, one, two) {
            const obj = {
              one: one,
			  two: two
            };
            return { ...oCol, ...obj };
        }

Tests:

empty obj
const empty = {}; const mergable = { one: 1, two: 2 }; const merged = { ...empty, ...mergable };
non empty obj
const nonEmpty = { zero: 0 }; const mergable = { one: 1, two: 2 }; const merged = { ...nonEmpty, ...mergable };
test 1
const obj = { zero: 0, ...standard() }
test 2
const obj = standard({ zero: 0 })
