Which statement correctly classifies the keys of ordinary JavaScript object properties?
Only strings and Symbols can be actual property keys✓Правильный ответ
Strings, Symbols, and Numbers remain distinct property-key types
Any primitive value remains unchanged when used as a property key
Every property key is stored as a Number
Объяснение
JavaScript ultimately represents every ordinary property key as either a string or a Symbol. A numeric expression may be used during access, but it is converted to a string key rather than remaining a Number key.
