Browser-friendly inheritance fully compatible with standard node.js inherits.
This package exports standard inherits from node.js
util module in node environment, but also provides
alternative browser-friendly implementation through browser field.
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 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
var inherits = require('inherits');
// then use exactly as the standard onenote 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 ofsuperfor referencing superclass - new version overwrites current prototype while old one preserves any existing fields on it
