How would I combine two arrays in Objective-C?

Question

What is the Objective-C equivalent of the JavaScript concat() function?

Assuming that both objects are arrays, how would you combine them?

Answer 1

Here's a symmetric & simple way by just beginning with an empty array:

NSArray* newArray = @[];
newArray = [newArray arrayByAddingObjectsFromArray:firstArray];
newArray = [newArray arrayByAddingObjectsFromArray:secondArray];
