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```

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
