| description.long | A tool for combining JavaScript modules into files that can run in web browsers, enabling developers to write code once and use it in both server and browser contexts. Includes support for source maps to maintain debugging visibility. | Rollup is a module bundler that compiles JavaScript code written as ES modules into various output formats for compatibility with different environments. It performs static analysis to eliminate unused code and can target modern browsers with native ES module support or legacy environments requiring CommonJS or UMD output. |
