The valueOf() method returns the primitive value of a Symbol object.

Syntax

Symbol().valueOf();

Return value

The primitive value of the specified Symbol object.

Description

The valueOf method of Symbol returns the primitive value of a Symbol object as a Symbol data type.

JavaScript calls the valueOf method to convert an object to a primitive value. You rarely need to invoke the valueOf method yourself; JavaScript automatically invokes it when encountering an object where a primitive value is expected.
