| Browser-friendly inheritance fully compatible with standard node.js | |
| [inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor). | |
| This package exports standard `inherits` from node.js `util` module in | |
| node environment, but also provides alternative browser-friendly | |
| implementation through [browser | |
| field](https://gist.github.com/shtylman/4339901). Alternative | |
| implementation is a literal copy of standard one located in standalone | |
| module to avoid requiring of `util`. It also has a shim for old | |
| browsers with no `Object.create` support. | |
| While keeping you sure you are using standard `inherits` | |
| implementation in node.js environment, it allows bundlers such as | |
| [browserify](https://github.com/substack/node-browserify) to not | |
| include full `util` package to your client code if all you need is | |
| just `inherits` function. It worth, because browser shim for `util` | |
| package is large and `inherits` is often the single function you need | |
| from it. | |
| It's recommended to use this package instead of | |
| `require('util').inherits` for any code that has chances to be used | |
| not only in node.js but in browser too. | |
| ## usage | |
| ```js | |
| var inherits = require('inherits'); | |
| // then use exactly as the standard one | |
| ``` | |
| ## note on version ~1.0 | |
| Version ~1.0 had completely different motivation and is not compatible | |
| neither with 2.0 nor with standard node.js `inherits`. | |
| If you are using version ~1.0 and planning to switch to ~2.0, be | |
| careful: | |
| * new version uses `super_` instead of `super` for referencing | |
| superclass | |
| * new version overwrites current prototype while old one preserves any | |
| existing fields on it | |
