Benchmark: Reduce vs Object.groupBy with function

Script Preparation code:

var max2 = 100000;

var data = [];
for (var i = 0; i <= max2; i++) { data.push({ id: i }); }

const getId = ({ id }) => id;

Tests:

New native groupBy
Object.groupBy(data, getId)
Old native reduce
data.reduce((acc, item) => { acc[getId(item)] = item; return acc; }, {})
