Thanks for supporting my open source work! 💖

I've been a JavaScript and regular expressions superfan for more than 15 years. My open source work has focused on projects that improve or make advanced use of regular expressions, and help others get the most from them.

Since 2007 I've been promoting and educating about the power of regular expressions — working to change perceptions of regexes as mysterious and unreadable magic. I've created and continue to contribute to numerous open source libraries and resources including:

• Created Regex+, which advances the state of the art for high-performance, readable, and maintainable native JavaScript regexes.
• Created Oniguruma-To-ES, an obsessively accurate transpiler for Oniguruma regexes; used by the Shiki syntax highligher.
• Created XRegExp, which was indispensable for heavy regex users in its time (especially during the ES3 to ES2017 era). XRegExp was influential on improvements to regexes in later ECMAScript standards, and many of its best features have been incorporated directly into modern JavaScript.
• Created RegexPal, the first web-based regex tester with regex syntax highlighting and real-time matching, which helped inspire later tools like RegExr and regex101.
• Created numerous other projects like Awesome Regex, parseUri, emoji-regex-xs, and regex-colorizer.

I've also coauthored O'Reilly Media's Regular Expressions Cookbook (translated into 7 languages) and High Performance JavaScript.

With your support, I'd love to spend more time contributing to open source and JavaScript improvements.
