Pass criteria

You pass when all six are true. Audit your work. Fix failures before continuing.

  • 5+ pure utility functions (no DOM, no I/O) with clear names
  • Used map/filter/reduce on real data — not index loops
  • Todo app: add, toggle, delete, filter, localStorage persist
  • No var, no == in new code
  • Code pushed to GitHub with meaningful commits
  • Can explain block scope vs function scope aloud in 60 seconds
