Furthermore, `Buffer` is a subclass of `Uint8Array`, +so the returned instances will have all the node `Buffer` methods and the +`Uint8Array` methods. Square bracket notation works as expected -- it returns a +single octet. + +The `Uint8Array` prototype remains unmodified. + + +## one minor difference + +#### In old browsers, `buf.slice()` does not modify parent buffer's memory + +If you only support modern browsers (specifically, those with typed array support), +then this issue does not affect you. If you support super old browsers, then read on. + +In node, the `slice()` method returns a new `Buffer` that shares underlying memory +with the original Buffer. When you modify one buffer, you modify the other. +[Read more.](https://nodejs.org/api/buffer.html#buffer_buf_slice_start_end) + +In browsers with typed array support, this `Buffer` implementation supports this +behavior. In browsers without typed arrays, an alternate buffer implementation is +used that is based on `Object` which has no mechanism to point separate +`Buffer`s to the same underlying slab of memory. + +You can see which browser versions lack typed array support +[here](https://github.com/feross/buffer/blob/master/index.js#L22-L48). + + +## tracking the latest node api + +This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer +API is considered **stable** in the +[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index), +so it is unlikely that there will ever be breaking changes. +Nonetheless, when/if the Buffer API changes in node, this module's API will change +accordingly. + +## related packages + +- [`buffer-equals`](https://www.npmjs.com/package/buffer-equals) - Node.js 0.12 buffer.equals() ponyfill +- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - A lite module for reverse-operations on buffers +- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - A simple module for bitwise-xor on buffers +- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package +- [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) - Convert a typed array to a Buffer without a copy + +## performance + +See perf tests in `/perf`. + +`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a +sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will +always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module, +which is included to compare against. + +NOTE: Performance has improved since these benchmarks were taken.
