27. throw & try/catch

Fail loudly, recover gracefully.

Write `parseAmount(str)` that throws `new Error("invalid amount")` for non-numeric input, and `safeParse(str)` returning 0 instead of throwing.

Required in your answer: throw new Errortrycatch

Runs in a sandboxed worker

function parseAmount(str) {
  // TODO

function safeParse(str) {
