Decorator can't be called

Question

I've started learning Typescript and now I'm learning about decorators but for some reason it just won't work even with the example code from the official website. I'll share you my code, maybe you can help me out here.

function Frozen(constructor: Function) {
    Object.freeze(constructor);
}



@Frozen
class Sample {
    id: number;

    constructor(id: number) {
        this.id = id;
    }
}

I do get the following error:

The runtime will invoke the decorator with 2 arguments, but the decorator expects 1.
