Introduction

IterizerJs makes it easier to write code that makes extensive use of ES6 iterables. It is not a polyfill, but merely makes it easier to get the most out of ES6 iterables and generators. It provides:

• A range() function so you never need to use the classic for loop again — for...of and for...in can be used instead.
• Implementations of the ES5 array methods (map(), filter(), every(), some(), reduce(), reduceRight(), indexOf() & lastIndexOf()) for use with any iterable.
• limit(), nthItem() and first() methods to reduce the number of items returned by long-running and infinite iterables.
• Other helpful methods like join(), toArray(), sum() & product().

By making extensive use of ES6 iterators, ES6 generators & the ES5 array methods, you can write more concise and more re-usable code — see the home page for more details.

You can run ES6 generators and iterators natively on the following platforms:

• Chrome 29 (the enable-javaScript-harmony flag must be enabled)
• Firefox 26.0
• Node.js 0.11.4 (the --harmony switch must be used)
• Older Browsers (by using regenerator to convert your code to ES5 you can run your code in most browsers)

Take a look at the home page for a more detailed explanation of why you might want to use IterizerJs.

Installing

NPM Instructions

If you use NPM then you should install as follows:

npm install iterizerjs

and start making use of iterizerjs using the following code:

var iterizerjs = require('iterizerjs');
iterizerjs.install();

Alternate Instructions

Alternatively, you can download the latest release, unzip, and start making use of iterizerjs using the following code:

<script src="dist/iterizer.js"></script>
<script>
	iterizerjs.install();
</script>

Running Tests

NPM Instructions

If you've installed via NPM you can run the tests as follows:

npm test

which runs all the tests in Node.js (using mocha), and the main spec tests in Firefox and Chrome (using karma). You can run the tests against Firefox and Chrome, with automatic re-runs as files are changed, using the command:

npm run test-browser

Finally, you also have the option to manually open 'spec/index.html' in the browser of your choice. To ensure that changes to the source code automatically cause the bundles to be re-built, you can run:

npm run watch

Alternate Instructions

If you haven't installed via NPM then there isn't too much point to running the tests since any changes to the source code won't be reflected. However, if you want to anyway, you can run the tests by opening 'spec/index.html' in the browser of your choice.
