1. var container = document.getElementById(‘container’);
2. for(var i = 0, len = someArray.length; i < len; i++) {
3. container.innerHtml += 'my number: ' + i;
4. console.log(i);
5. }

Instead if using len=somearray.length in the for loop, please move this outside as a variable and use it. Every time, finding the length is not a good idea.

1. var container = document.getElementById('container');
var iArrLenTmp = someArray.length;
2. for(var i = 0, len = iArrLenTmp; i < len; i++) {
3. container.innerHtml += 'my number: ' + i;
4. console.log(i);
5. }

Great stuff, Jeff!

Only one suggestion. I know I use the term “self-executing functions” too, but at some point saw Doug Crockford using the term “immediate function” and it kinda rolls out the tongue easier

Another Great book is JavaScript the Missing Manual, it includes some jquery and is an overall very easy read. The Author make real life connections, and adds a little humor.
