  • no dependancies
  • works in node.js and browser
  • support source maps
  • works with es2015 and react/jsx
  • even works with new es6 arrow function
  • easily integrable in modern js tools. browserify/webpack/gulp you name it

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
