I try but continue to be enable of developing complex code in javascript. It is so different when compared to Java/.NET where organizing large code blocks and making sure the pieces work well together is so easy. Very frustrating as there is so much that can be done on a browser but hampered by a development environment not much different from only using a text editor.
