Well, that's true, the docs are terrible; you're way better off finding videos of people using the environment and eventually just learning to experiment with it. Largely what's different is that everything is live, all text is code and all code is text and you can highlight anything anywhere and execute it via either context menu or hotkeys. Pays to learn the hotkeys. Pays to learn to use hotkey for inspector and evaluator; inspectors are amazing, working with an object model without a database needing to be behind it is amazing, it lets you prototype extremely fast. And finally, the language itself is amazing as it's a programmable programming language, you can extend it to work to your will with very nice internal DSL's largely thanks to cascades and a clean anonymous function syntax.
