What is a key difference in how forEach and map handle array elements?
- forEach returns a new array, while map mutates the original array
- forEach is synchronous, while map is asynchronous
- forEach is purely for iteration, while map is for transformation and returns a new array
- map modifies the original array in place, while forEach creates a new array
The key difference is that forEach is primarily for iteration and doesn't return a new array, whereas map is used for transformation and creates a new array with the results of applying a function to each element of the original array.
