each()

The each method iterates over the items in the collection and passes each item to a callback:

let sum = 0;

const collection = collect([1, 3, 3, 7]);

collection.each(item => {
  sum += item;
});

//=> console.log(sum);
//=> 14

If you would like to stop iterating through the items, you may return false from your callback:

let sum = 0;

const collection = collect([1, 3, 3, 7]);

collection.each(item => {
  if (item > 3) {
    return false;
  }

  sum += item;
});

//=> console.log(sum);
//=> 7
