Common Mistakes to Avoid

⚠️

Regex syntax errors

Solution: Test regex pattern separately first. Backslashes may need escaping.

⚠️

Too greedy patterns

Solution: .+ captures too much. Use .+? for lazy matching or more specific patterns.

⚠️

Missing matches

Solution: Regex may be too restrictive. Use flags like case-insensitive if needed.
