map()
The map method iterates through the collection and passes each value to the given callback. The callback is free to modify the item and return it, thus forming a new collection of modified items:
const collection = collect([1, 2, 3, 4, 5]);
const multiplied = collection.map(item => item * 2);
multiplied.all();
// [2, 4, 6, 8, 10]
Like most other collection methods,
mapreturns a new collection instance; it does not modify the collection it is called on. If you want to transform the original collection, use thetransformmethod.
