Package Exports

value-equal

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (value-equal) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

value-equal

value-equal determines if two JavaScript values are equal using Object.prototype.valueOf.

In many instances when I'm checking for object equality, what I really want to know is if their values are equal. This is good for:

Stuff you keep in localStorage
window.history.state values
Query strings

Installation

Using npm:

$ npm install --save value-equal

Then with a module bundler like webpack, use as you would anything else:

// using ES6 modules
import valueEqual from 'value-equal';

// using CommonJS modules
var valueEqual = require('value-equal');

The UMD build is also available on unpkg:

<script src="https://unpkg.com/value-equal"></script>

You can find the library on window.valueEqual.

Usage

valueEqual(1, 1); // true
valueEqual('asdf', 'asdf'); // true
valueEqual('asdf', new String('asdf')); // true
valueEqual(true, true); // true
valueEqual(true, false); // false
valueEqual({ a: 'a' }, { a: 'a' }); // true
valueEqual({ a: 'a' }, { a: 'b' }); // false
valueEqual([1, 2, 3], [1, 2, 3]); // true
valueEqual([1, 2, 3], [2, 3, 4]); // false

That's it. Enjoy!
