I have HTML Scripts for a variety of webpages that I haven't overlooked at all and another question: do you need a program like Dreamweaver to create JavaScripts
For JavaScript coding you can use free software from netbeans.org Or you can Google for keywords "JavaScript ide" - there are a lot of tools which helps to create JavaScript.
Most developers don't use complicated IDE to code, they use notepad-like programs with syntax highlighting and hardcoded them. I personally find it comfortable. Notepad ++ or PSPad are some examples of the good tools.
