If you're a server-side programmer like me, javascript is a language you learn just to get by on. However, in my case, I never took the time to fundamentally learn the language. I would pick it up along the way to because i needed to, or because i was forced to used it.<p>Then of course jquery came long, which made using javascript a whole lot easier. However, whenever it came to writing raw js code, (instead of copying and pasting snippets off another site.) i was lost. Especially when it came to writing proper oop, or using closures. - these problems also slowed down my productivity time, as well, leaving a frustrating experience in memory.<p>The youtube link: http://www.youtube.com/watch?v=hQVTIJBZook is Doug Crockford talking about misconception about javascript.<p>He also wrote a book called: "Javascript: The Good Parts" - which many JS coders are probably be already familiar with<p>I would also recommend (which is recommended by many other programmers): JavaScript - The Definitive Guide
