TIDE is a Tiny IDE for JavaScript. Its purpose is to write, analyze or debug small JavaScript programs. The current version 2.0 is still beta and has some bugs, but it is already better than the previous version. Please note that it might not run all JavaScript programs correctly, but the provided examples should all work.
