ChitChat is a toy for programming in JavaScript.
Writing JavaScript with ChitChat is really easy:
Open the canvas
Write some JavaScript in the text box (see the examples for help getting started)
Click "Run" to run your JavaScript
Every time you run your program by clicking "Run", ChitChat saves the current version of your program; a new link with the current time appears in a bar above the text box. You can jump back and forth between versions of your program by clicking these time links. ChitChat remembers the last 10 versions of your program.
To permanently save your work, just save the canvas web page on your computer. (For most browsers, this is under the File menu and says something like "Save Page As...".) When you open that file, you will see your code and its recent checkpoints are just as they were when you saved it.
