Hanselminutes #256: JavaScript & jQuery: Moving beyond Alert()

Dave Ward ( @encosia ) and I were honored to be guests on Hanselminutes #256: JavaScript & jQuery: Moving beyond Alert() while we were at the MVP Summit in Redmond, WA.

Listen to Podcast

Our conversations revolved around trying to encourage developers to take their JavaScript knowledge to the next level.

Many developers view JavaScript as a necessary evil and possibly a toy language. Part of this tarnished view of JavaScript may have stemmed from the olden days when you had to manually navigate through the various DOM inconsistencies yourself. Thankfully today modern JavaScript libraries (such as jQuery, Dojo, MooTools, YUI, etc) have abstracted away many of those horrible cross-browser inconsistencies in the DOM.

Many developers don't take the necessary effort to learn JavaScript appropriately. What typically happens is that a developer will try to code JavaScript in the same way they would C#, Java, etc... In many cases, you can be successful with this approach, however, the more JavaScript you write you will inevitably find yourself uncovering strange bugs.

Lint Tools
These are some tools that can help you identify some common problems in your JavaScript
  • by Douglas Crockford *Based on the concepts from the JavaScript: The Good Parts book
  • by Anton Kovalyov ( @antonkovalyov ) *A JavaScript Community fork of JSLint

Script Loaders
A way to load your scripts asynchronously so that your pages can load faster

HTML5 Libraries
Detects features of your browser so that you can use it or pollyfill with JavaScript

These are some good books to introduce you to JavaScript, show you what you what parts are good, and also good patterns that you should consider.

These articles are targeted for C# developers that want to understand JavaScript better.d

These are some great videos that I have learned a lot from. If you have time I strongly encourage you sit back and enjoy.
