A proposal to make grouping of items in an array easier.
const array = [1, 2, 3, 4, 5];
// groupBy groups items by arbitrary key.
// In this case, the we're grouping on even/odd keys
array.groupBy(i => {
return i % 2 === 0 ? 'even': 'odd';
});
// => { odd: [1, 3, 5], even: [2, 4] }- Justin Ridgewell (@jridgewell)
