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