Symbol.description — empty string

📖 Usage Example
const s = Symbol('')
s.description            // → ''
s.description === undefined  // → false

An empty string is a valid description — distinct from having no description at all.

Symbol With Empty String Description

Passing an empty string '' gives a .description of '', which is different from undefined.

Challenge: Verify the empty string case.

💡 Hints (1)
  • • Empty string '' is a valid description — it is not the same as undefined.
