Here are my usual mystakes during programming:
- mismatching syntax (parentheses, braces, etc.)
- I often forget variable names and built-in functions
- I often use methods and functions with wrong parameters
- I often crash browsers with endless loops
- I usually forget to use proper indentation (although I comment my code very well and appropriately.. oh, I think it's Scite's fault.. that's an excuse)
- I'm still looking for the perfect programming editor (if it does exist).
