First, let’s look at very lightweight, but powerful boilerplate, an adapter that will let you write a module for both AMD and CommonJS standard module systems, using AMD style dependency declarations. This combination allows us to create modules that can be used both in browser and server environments:

1.7 Preview
View 7.js
/*
Dave Methvin, Rick Waldron, Corey Frang, Timmy Willison and a handful of other developers working with the jQuery project have been hard at work this week landing a number of new features into jQuery core. The project is currently preparing to roll out version 1.7 of the popular library sometime during October.
Whilst patches and other commits are still being landed, I thought it would be interesting to take you through some of the new features you can expect to see in jQuery 1.7 through live examples. All of these can be played around with using our up-to-the minute version of jQuery (git or 'edge' as it's sometimes referred to) and should be cross-browser compatible.
The first feature to land that I've been quite excited about has been support for registering jQuery as a CommonJS-compatible asynchronous module. This is something that wouldn't have been possible without the dedication of RequireJS author James Burke, who was responsible for much of the work that went into the commit.

Workbox runtime caching recipes

Your Service Worker script will need to import in Workbox and initialize it before calling any of the routes documented in this write-up, similar to the below:

importScripts('workbox-sw.prod.v1.3.0.js');
const workbox = new WorkboxSW();

A (very) WIP collection of optimized/recommended jQuery plugin patterns

Disclaimer:
-----------------------
Whilst the end-goal of this gist is to provide a list of recommended patterns, this
is still very much a work-in-progress. I am not advocating the use of anything here
until we've had sufficient time to tweak and weed out what the most useful patterns

#Lessons From A JavaScript Code Review

I was recently asked to review some code for a new JavaScript application and thought I might share some of the feedback I provided as it includes a mention of JavaScript fundamentals that are always useful to bear in mind. Code reviews are possibly the single biggest thing you can do to improve the overall quality of your solutions and if you're not actively taking advantage of them, you're possibly missing out on bugs you haven't noticed being found or suggestions for improvements that could make your code better.

##Challenges & Solutions

Code reviews go hand-in-hand with maintaining strong coding standards. That said, standards don't usually prevent logical errors or misunderstandings about the quirks of a programming language. Even the most experienced developers can make these kinds of mistakes and code reviews can greatly assist with catching them.

Often the most challenging part of code reviews is actually finding an experienced developer you trust to complete

Limit the frame-rate being targeted with requestAnimationFrame

limitLoop.js - limit the frame-rate when using requestAnimation frame
Released under an MIT license.
When to use it?
----------------
A consistent frame-rate can be better than a janky experience only
occasionally hitting 60fps. Use this trick to target a specific frame-
rate (e.g 30fps, 48fps) until browsers better tackle this problem
