How can I improve the performance of my regex patterns?

To improve regex performance, consider simplifying your patterns, using non-capturing groups, and avoiding backtracking.

What are non-capturing groups and how do they help?

Non-capturing groups, denoted by (?:...), allow you to group patterns without creating backreferences, reducing overhead.

Are there specific regex patterns that are known to be slow?

Yes, patterns with excessive backtracking, like nested quantifiers, can be particularly slow. Try to avoid them.

Can you suggest tools to test regex performance?

Sure! Tools like Regex101 and RegExr allow you to test and analyze the performance of your regex patterns.
