Rehber
Regex Tester is a free online tool for checking JavaScript regular expressions against real sample text before you use them in code, forms or scripts.
It is useful when you need to validate patterns, inspect matches, test flags and understand why a regex is matching too much, too little or the wrong text.
Use it when a plain contains search is not enough and you need a pattern that can validate, extract or transform text based on rules.
It is especially useful before shipping a regex into production code, because testing against real examples helps expose false positives, missed matches and flag mistakes.
Kullanim
Paste the sample text, add the regex pattern and choose the flags you want to test.
Run the tester and inspect the matches, groups and overall behavior to make sure the pattern is doing exactly what you expect.
If the result looks wrong, adjust escaping, anchors, quantifiers or flags before copying the regex into your codebase.
