What is the difference between $.map and $.grep in jQuery

Question

What is the difference between $.map and $.grep in jQuery?

I want a simple answer as far as possible.

Answer 1

I will assume you mean $.grep and $.map. The difference is that we use $.grep to filter an array while we use $.map to apply a function to each item in the array.

Here is a much better explanation than I can make:
