Question

I’m looking for a way to remove the comma and all that comes after it in a string, for example:

important, not so important

I’d like to remove “,not so important”

Any ideas? Thanks in advance!

Answer 1

You can do it with substring and indexOf:

str = str.substring(0, str.indexOf(','));

but you’d have to be sure that a comma is in there (test it before).

Another possibility is to use split():

str = str.split(',')[0];

this works even without testing beforehand but might perform unnecessary string operations (which is probably negligible on small strings).
