Description

The [@@toPrimitive]() method of Symbol returns the primitive value of a Symbol object as a Symbol data type. The hint argument is not used.

JavaScript calls the [@@toPrimitive]() method to convert an object to a primitive value. You rarely need to invoke the [@@toPrimitive]() method yourself; JavaScript automatically invokes it when encountering an object where a primitive value is expected.
