Javascript editor & runner? (For Beginner)?

[Visualfield549]

So I need to code an application in Javascript, and I have absolutely no idea where to start to be honest. I need a program that can do everything, code it and run it. I am a complete rookie but I do believe im looking for a WYSIWYG type java coder. Appreciate any recommendations, thank you.
@Lunji: Gotcha, what coder are you currently using?

For javascript you gotta run it in your browser just put it in a little html file which contains about 20 lines of code.

I like Komodo Edit but many also recommend Notepad++.

JavaScript is most often used client-side in a web browser in conjunction with HTML and CSS. You can see the console by pressing F12 in your browser of choice. From there you can set break points and all that other debugging stuff.

If you're using Google Chrome or Firefox then I recommend downloading Firebug instead of using the built-in developer tools but that's just me.

Oh, Java and JavaScript aren't related programming languages so if you don't want people to jump down your throat about it, use the right word. ^_^
