WhiteSpace an issue?

I have a List Object with a few Items listed. Instead of making an Event for every List Item, I want to set a LocalStorage Key to List.SelectedText.

I am curious if whitespace matters in LocalStoarge Key values, Variable values or Function names. Will it cause any issues on any devices?

Is there an expression to get rid of whitespace in the string? I tried trim() but found out it only removes extra whitespace before or after the string and not in the string.

I thought about that after posting, but wasn't sure about it. I tried it after your post though. It took me a few tries, but I figured it out replace(List.SelectedText," ","")
