20. Redacting secrets before logging

Never log a private key or seed.

Write `redact(obj)` returning a shallow copy where values for keys `"privateKey"`, `"mnemonic"` or `"seed"` are replaced with `"[redacted]"`.

Required in your answer: redacted

Transpiled, then run in a sandbox

function redact(obj) {
  // TODO
}
