Object cannot be converted to another data type?

Question

JavaScript

A question. Why does the operator typeofstill return , after converting an object to a primitive data type object?

let a = {
};
console.log(String(a)); //преобразование к строке
console.log(typeof a); //object

Does this mean that the conversion can only occur to hints, BUT not to data types (that is, hints can be different, but the data type is always the same - an object)?

Or does the conversion to other data types occur, and this is just a JS error (like, for example typeof function => function)?

Answer 1

String(a) returns the result of the transformation, but the original object remains unchanged.

const strA = String(a)
typeof strA // string
