Remove a value from an array in CoffeeScript

Question

I have an array:

array = [..., "Hello", "World", "Again", ...] 

How could I check if "World" is in the array? Then remove it if it exists? And have a reference to "World"?

Sometimes maybe I wanna match a word with a regexp and in that case I won't know the exact string so I need to have a reference to the matched String. But in this case I know for sure it's "World" which makes it simpler.

Thanks for the suggestions. I found a cool way to do it:

filter() is also an option:

arr = [..., "Hello", "World", "Again", ...]  newArr = arr.filter (word) -> word isnt "World"
