Difference between map and collect in Ruby?

Question

I have Googled this and got patchy / contradictory opinions - is there actually any difference between doing a map and doing a collect on an array

Answer 1

The collect and collect! methods are aliases to map and map!, so they can be used interchangeably. Here is an easy way to confirm that:

Array.instance_method(:map) == Array.instance_method(:collect)
 => true
