Frequently asked questions
Which regex flavor do these use?
They use JavaScript (ECMAScript) regular expression syntax, the same engine that runs in browsers and Node.js. Most patterns transfer to other languages with minor tweaks.
Can I test a pattern against my own text?
Yes — each pattern has a live tester that shows whether your input matches as you type.
