Splitting string with regular expression to make it array without empty element

Question

Here, I have example javascipt string:

example_string = "Answer 1| Answer 2| Answer 3|";

I am trying to get array like this using regular expression:

Array ["Answer 1", " Answer 2", " Answer 3"]

I have tried:

result = example_string.split('/[|]+/g');

and also with the following patterns

'/[|]+/g'
'/[|]+\b/g'
'/[|]+[^$]/g'

And I am still getting an array with empty element at the end of it:

 Array ["Answer 1", " Answer 2", " Answer 3", ""]

That cause me lot of trouble. Does anyone know where I am making mistake in my pattern or how to fix it?

Answer 1

I always liked matching everything I always hated split but:

Regex for splitting: (\|(?!$)) DEMO

Matching instead of splitting:

Regex: (?:([\w\s]+)\|?)

You can even use [^\|]+ To match whatever you have to match BUT |
