- 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
