JS Practice — Built-in Objects

Symbol.for() — description matches key

📖 Usage Example

const s = Symbol.for('id')
s.description   // → 'id'

For global symbols, .description is always equal to the registration key.

Symbol.for Description

For a symbol created with Symbol.for('x'), the .description is 'x'.

Challenge: Verify the description of a global symbol.
