I make this mistake over and over.  It took me years to learn to declare variables NOT at the top of functions but to declare them close to where I use them.  Well, not so much the case in JavaScript.  Say for example you have two for loops that operate on the same variables.   My expectation from years of experience is to do the following:
  • 3
  • 0
  • 123
  • 32
