Re^6: Order in which grep/map receive elements

[jwkrahn]

Grep receives an array and returns an array.

What is the difference between a list and an array?

grep receives a LIST and returns a LIST.

[greengaroo]

Well, I have used the wrong term. A List is a series of ordered elements. An Array, in Perl, is a variable that contains a List, but a List is not necessarily always an Array. This: (1,2,3) is a List but its not an Array variable.

Sorry about that, I didn't meant to confuse anyone.

Thank you jwkrahn for pointing it out!
