es5-ext

es5-ext - ECMAScript5 extensions

Useful functions and objects that are not part of the standard.
It's work in progress, new methods are added when needed.

Installation

Can be used in any environment that implements ES5.
In implementations that are stuck to ES3 it will work with es5-shim.

To use it with node:

$ npm install es5-ext

Usage

Recommended way is to require stuff you need individually:

var sequence = require('es5-ext/lib/Function/sequence')
  , merge = require('es5-ext/lib/Object/merge').call;

sequence(...);
merge(...);

but you can grab whole packs:

var fnExt = require('es5-ext/lib/Function');

fnExt.curry(...);
fnExt.sequence(...);

and if you prefer take them all:

var ext = require('es5-ext');

ext.Function.curry(...);
ext.Function.sequence(...);
ext.Object.merge.call(...);

• Object.isPlainObject()
• Object.link(p)
• Object.merge(p)
• Object.pluck(name)
• Object.set()
• Object.setTrue()
