Use cases

• Improve your tests
  • jsdoced javascript will detect a new kind of errors.
  • So this is an additional level of testing
  • better detect those bugs before your users see them :)
• Debug build for library
  • any library provide a minified version and a normal version
  • You can provide a jsdoced version
  • this debug version contains additional code to help debug.
  • thus people can use this one when developping or testing their own project
  • and hopefully detect errors earlier.
  • Specially interesting when you are learning a library. because you are more likely to do mistakes. better for your users :)
  • see /examples/gulpfile for a example on how to that with gulp
