 A lightweight **Oniguruma to JavaScript RegExp transpiler** that runs in the browser and on your server. Use it to:
 
-- Take advantage of Oniguruma's extended regex capabilities in JavaScript.
+- Take advantage of Oniguruma's many extended regex featrures in JavaScript.
 - Run regexes intended for Oniguruma in JavaScript, such as those used in TextMate grammars (used by VS Code, [Shiki](https://shiki.matsu.io/) syntax highlighter, etc.).
 - Share regexes across your Ruby and JavaScript code.
 
-Compared to running the actual [Oniguruma](https://github.com/kkos/oniguruma) C library in JavaScript via WASM bindings (e.g. via [vscode-oniguruma](https://github.com/microsoft/vscode-oniguruma)), this library is **much lighter weight** and its regexes **run much faster** since they run as native JavaScript.
