This question pertains to the built-in Number object as a primitive wrapper.
let n = new Number(2);
console.log(n); // Number {}
console.log(typeof n); // "object"
n++;
console.log(n); // 3
console.log(typeof n); // "number"
I have observed that JavaScript is automatically performing typecasting in this scenario. Specifically, it is converting the Number object to a number primitive. Is there a method to modify the Number object directly without undergoing this type of conversion?
It is not possible to change a Number instance as they are immutable. Instead, you would need to create a new instance like this:
n = new Number(++n);
This will give you a new instance that is one number bigger than the previous instance.
