fun with apply

[Betelgeuse]

Apply is a fun function it runs a given function with the given arguments.

(apply function argList)

Some uses are saving functions for later use. (like saving the functions in a list to apply them later)

A cool use is working with lists of numbers. Say you wanted the sum of all the numbers in a list all you would have to do is (apply add numberList) and it will return the sum.
