replace()
The replace method behaves similarly to merge; however, in addition to overwriting matching items with string keys, the replace method will also overwrite items in the collection that have matching numeric keys:
const collection = collect({
name: 'Bob',
});
const replaced = collection.replace({
name: 'John',
number: 45,
});
replaced.all();
// {
// name: 'John',
// number: 45,
// }
