The valueOf() method of Symbol values returns this symbol value.
Syntax
valueOf()
Parameters
None.
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.
Examples
Using valueOf()
const sym = Symbol("example");
sym === sym.valueOf(); // true
