debug.js: javascript made easy to debug

Javascript was slow and hard to debug for a long time. Now it is no more slow. But it is still hard to debug. debug.js proposes to fill this gap and provides a bunch of practical tools which makes your javascript code much easier to debug.

• With debug.js, your classes can declare functions and property as private/public. Thus if a private function is called from an unauthorised location, you will be immediatly warned.
• With debug.js, you can declare attributes to functions e.g. you can mark it as deprecated, and be notified when it is used. You can trigger performance profiling on this function and see if it needs optimisation. You can track who is using it. You can put conditional breakpoint.
• With debug.js, you can have strong type checking. It will check the parameters type and numbers of a function when it is called. If you expect to get a Number and a String, debug.js will check and notifies you when it happens to be wrong. It is even possible to do that on any object property.
• With debug.js, it is possible to automatically detect your global variable, then to automatically local is using them, thus you can remove them easily.

• console.log to filter by origin
  • DONE not tested
