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()
js
const sym = Symbol("example");
sym === sym.valueOf(); // true
