Some lessons and things I've learned:

  • .reduce() is great at performing operations on arrays
  • It might not be as readable, but you can add true and false as 1 and 0
  • If you want to copy an array to manipulate, be sure to create a new array (like [...array])
  • Classes and recursion can be used for nesting problems in a pinch
  • Loops in loops? Use references to determine what to break from
