For now, just a list, and we fully expect to make all of these mistakes. We will return to this post whenever we do to update it with examples.

• Incorrect references to this
• Assuming a block-level scope
• Creating (a) memory leak(s)
  • Dangling references to defunct objects
  • Circular references
• Equality confusion
• Inefficient DOM manipulation
• Not using the features of prototypal inheritance
