How to remove double underscore using JavaScript [duplicate]

Question

How do I remove double or multiple underscores in a string using JavaScript?

E.g.

stack__overflow___website

I will need to eliminate the __ and replace it with a single _.

Answer 1

You can use replace() with a regex to match consecutive underscores:

'stack__overflow___website'.replace(/_+/g, '_')

Answer 2

var myString = "stack__overflow___website",
    myFormattedString = myString.split('__').join('_');
