A regex wizard's best friend, always.
When you want to match zero or more occurrences of a pattern, you've come to the right place.
Use \{0,} to match zero or more of the pattern before the quantifier.
For example, ab{0,} will match an 'a' followed by zero or more 'b's.
Or, ab{0,}c will match an 'a' followed by zero or more 'b's, then a 'c'.
But wait, there's more! Learn about optional quantifiers.
