Access values in nested properties and arrays using a keypath.
npm install keypathKeypath
-------
Easily access properties in nested objects and arrays using a dot notation
syntax.
Install with NPM:$ npm install keypath
Keypath only exposes one function, so require it and use it.
var keypath = require('keypath');
keypath('foo.bar.baz', object);
Keypath takes 2 or 3 arguments.
* keypath: a string representing the value you want to access.
* object: the object in which this value resides.
* callback/rethrow: an optional argument that can be either a function or
true. If you give it a function, this function will be called if an error
occurs. The error itself will be the callbacks only argument.
If you pass true any error will be re-thrown and you can catch it
yourself.
If left out keypath() will just return undefined.
I'd like to add setting, that'd be convinient, right? Also adding@avg and
the like would be cool. If you don't know what that is read this
excellent blogpost about
that feature in Cocoa.
