Javascript: Some useful sites that helps.

Frankly speaking, I don't have a fantastic memory and in case, you don't have a fantastic memory, you probably can use the following sites to search for useful examples and references. Even though these sites doesn't provide an example for all everything, but it's a great place to start searching.

W3Schools This has been around for quite some time. Not only it covers 'Javascript', it also covers coding environment like 'PHP', 'SQL', 'ASP.NET', etc... Though most of the time it covers only the basic stuff, but it's a great place to get you started.

JavaScripture This covers JavaScript only. But with the number of examples that was provided on the site itself to demonstrate the usage of the different types of JavaScript syntax, makes this a pretty good place to start searching.
