Question

I have a question, and I’m sure there is a relatively simple answer to this, but at the moment I’m having a massive brain fart and can’t seem to think of an elegant solution that doesn’t involve a ridiculous myriad of if statements.

Basically, I have a web page that is dynamically updating the users present into a string, stylised as such

User1, User2, User3, User4

However, when I delete one of these users, from a different location, they are removed from the list, but I’m left with the following

Beginning

, User2, User3, User4

Middle

User1, , User3, User4

End

User1, User2, User3,

If anyone knows of a relatively easy way to remove these unwanted commas, that would be really helpful; it’s been bugging me for hours.

Answer 1

You could match ,$, ^, and , , with a regex and replace it with empty
