The buffer module from node.js, for the browser.
The buffer project is a Node.js Buffer implementation for web browsers, enabling developers to manipulate binary data in browser environments using the exact same API as Node.js. Built in JavaScript and backed by Typed Arrays (Uint8Array and ArrayBuffer), it offers a compact bundle size of 6.75KB minified and gzipped while maintaining compatibility across modern browsers including Chrome, Firefox, Edge, and Safari. The project was originally created by Feross Aboukhadijeh and is designed to work seamlessly with browserify, allowing npm modules that depend on Node's Buffer API to function in browser contexts without modification.
