Caveats and Notes

  • Applies the callback to each element
  • You cannot "break" or "continue" as you can with a for loop
  • By default, forEach does not mutate the array
  • If you mutate it in process, you will have interesting issues
  • Curly braces matter in multiple statements
  • parenthesis matters with multiple parameters in the forEach call back function requiring value,index,array but if you have only one parameter, then okay to delete parenthesis
