Remove a value from an array in CoffeeScript

Tags: , ,

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:


array.indexOf("World") will get the index of "World" or -1 if it doesn’t exist. array.splice(indexOfWorld, 1) will remove "World" from the array.
