This is an excellent point, but note that where the intent is to avoid an undefined value, the defined-or operator // is a better choice than the logical-or operator ||, because:

  1. It will not override a false value (such as the empty string) in an already-defined variable.
  2. It makes the intention of the code clearer.

Hope that’s of interest,
