1Browser-friendly inheritance fully compatible with standard node.js 2[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor). 3 4This package exports standard `inherits` from node.js `util` module in 5node environment, but also provides alternative browser-friendly 6implementation through [browser 7field](https://gist.github.com/shtylman/4339901). Alternative 8implementation is a literal copy of standard one located in standalone 9module to avoid requiring of `util`. It also has a shim for old 10browsers with no `Object.create` support. 11 12While keeping you sure you are using standard `inherits` 13implementation in node.js environment, it allows bundlers such as 14[browserify](https://github.com/substack/node-browserify) to not 15include full `util` package to your client code if all you need is 16just `inherits` function. It worth, because browser shim for `util` 17package is large and `inherits` is often the single function you need 18from it. 19 20It's recommended to use this package instead of 21`require('util').inherits` for any code that has chances to be used 22not only in node.js but in browser too. 23 24## usage 25 26```js 27var inherits = require('inherits'); 28// then use exactly as the standard one 29``` 30 31## note on version ~1.0 32 33Version ~1.0 had completely different motivation and is not compatible 34neither with 2.0 nor with standard node.js `inherits`. 35 36If you are using version ~1.0 and planning to switch to ~2.0, be 37careful: 38 39* new version uses `super_` instead of `super` for referencing 40 superclass 41* new version overwrites current prototype while old one preserves any 42 existing fields on it 43
