You’ve heard it many times before: make sure your JavaScript plays nice with other code, especially if you package it up as a plugin and share with other developers. Perhaps the most obvious thing to think about is global variables, which you want to avoid creating since they can easily clash with other global variables.
How you apply and remove event handlers may also cause problems that can be really hard to troubleshoot. Recently I was working on a project where I had attached a function to the window.resize event. But my function simply would not run, and it took me forever to figure out why.
