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.
