Read the\n[official docs](http://iojs.org/api/buffer.html) for the full list of properties,\ninstance methods, and class methods that are supported.\n\n## features\n\n- Manipulate binary data like a boss, in all browsers -- even IE6!\n- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)\n- Extremely small bundle size (**5.04KB minified + gzipped**, 35.5KB with comments)\n- Excellent browser support (IE 6+, Chrome 4+, Firefox 3+, Safari 5.1+, Opera 11+, iOS, etc.)\n- Preserves Node API exactly, with one important difference (see below)\n- `.slice()` returns instances of the same type (Buffer)\n- Square-bracket `buf[4]` notation works, even in old browsers like IE6!\n- Does not modify any browser prototypes or put anything on `window`\n- Comprehensive test suite (including all buffer tests from node.js core)\n\n\n## install\n\nTo use this module directly (without browserify), install it:\n\n```bash\nnpm install buffer\n```\n\nThis module was previously called **native-buffer-browserify**, but please use **buffer**\nfrom now on.\n\nA standalone bundle is available [here](https://wzrd.in/standalone/buffer), for non-browserify users.\n\n\n## usage\n\nThe module's API is identical to node's `Buffer` API. Read the\n[official docs](http://iojs.org/api/buffer.html) for the full list of properties,\ninstance methods, and class methods that are supported.\n\nAs mentioned above, `require('buffer')` or use the `Buffer` global with\n[browserify](http://browserify.org) and this module will automatically be included\nin your bundle. Almost any npm module will work in the browser, even if it assumes that\nthe node `Buffer` API will be available.\n\nTo depend on this module explicitly (without browserify), require it like this:\n\n```js\nvar Buffer = require('buffer/').Buffer // note: the trailing slash is important!\n```\n\nTo require this module explicitly, use `require('buffer/')` which tells the node.js module\nlookup algorithm (also used by browserify) to use the **npm module** named `buffer`\ninstead of the **node.js core** module named `buffer`!\n\n\n## how does it work?\n\n`Buffer` is a subclass of `Uint8Array` augmented with all the `Buffer` API methods.\nThe `Uint8Array` prototype is not modified.\n\n\n## one minor difference\n\n#### In old browsers, `buf.slice()` does not modify parent buffer's memory\n\nIf you only support modern browsers (specifically, those with typed array support),\nthen this issue does not affect you. If you support super old browsers, then read on.\n\nIn node, the `slice()` method returns a new `Buffer` that shares underlying memory\nwith the original Buffer. When you modify one buffer, you modify the other.\n[Read more.](http://iojs.org/api/buffer.html#buffer_buf_slice_start_end)\n\nIn browsers with typed array support, this `Buffer` implementation supports this\nbehavior. In browsers without typed arrays, an alternate buffer implementation is\nused that is based on `Object` which has no mechanism to point separate\n`Buffer`s to the same underlying slab of memory.\n\nYou can see which browser versions lack typed array support\n[here](https://github.com/feross/buffer/blob/master/index.js#L20-L46).\n\n\n## tracking the latest node api\n\nThis module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer\nAPI is considered **stable** in the\n[node stability index](http://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),\nso it is unlikely that there will ever be breaking changes.\nNonetheless, when/if the Buffer API changes in node, this module's API will change\naccordingly.\n\n## performance\n\nSee perf tests in `/perf`.\n\n`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a\nsanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will\nalways be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,\nwhich is included to compare against.\n\n### Chrome 38\n\n| Method | Operations | Accuracy | Sampled | Fastest

npm install\n\nThen, to run tests in Node.js, run:\n\n npm run test-node\n \nTo test locally in a browser, you can run:\n\n npm run test-browser-local\n \nThis will print out a URL that you can then open in a browser to run the tests, using [Zuul](https://github.com/defunctzombie/zuul).\n\nTo run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:\n\n npm test\n \nThis is what's run in Travis, to check against various browsers. The list of browsers is kept in the `.zuul.yml` file.\n\n## JavaScript Standard Style\n\nThis module uses [JavaScript Standard Style](https://github.com/feross/standard).\n\n[](https://github.com/feross/standard)\n\nTo test that the code conforms to the style, `npm install` and run:\n\n ./node_modules/.bin/standard\n\n## credit\n\nThis was originally forked from [buffer-browserify](https://github.com/toots/buffer-browserify).\n\n\n## license\n\nMIT.
