Douglas Crockford: The JavaScript Programming Language

In this 2007 presentation at Yahoo!, which is meant to be the beginning of a three-course sequence (followed by "Theory of the DOM" and then "Advanced JavaScript"), Douglas Crockford explores not only the language as it is today but also how the language came to be the way it is.

Note: there's a title at the opening that claims this is "Part 1 of 4", but this video contains all four parts edited together. No need to go searching for the missing parts.

Does this contain the "Advanced Class"?

I was not able to reproduce the behavior that Doug described in the lecture between 50:08 ~ 50:25. Here is my testing code: var oA = {name:"Doug"};  var oB = object(oA); oB.name="NewName"; delete oB["name"]; alert(oB.name); //display "undefined" instead of "Doug". Not sure what I did wrong.

if you say `new Boolean('false')`, it's value is false, but the value is truthy

:facepalm:

In case you want to try it out...

function fade(id) { var dom=document.getElementById(id­), level = 1; function step() { var h = level.toString(16); var newColor = '#FFFF' + h + h; dom.style.backgroundColor = newColor; if (level<15) { level += 1; setTimeout(step,100); } } setTimeout(step,100);

}

It's named 'Douglas Crockford: An Inconvenient API - The Theory of the DOM'

What better way to learn the fundamentals of javascript than learning them from the js guru Douglas Crockford.

@Doug, Thanks a lot for that amazing lecture. Really appreciate it.
