How do I implement decorators in TypeScript?

In TypeScript, decorators are special functions that can be attached to classes, methods, or properties. They allow you to modify the behavior of the target. Would you like a simple example?

Yes, please provide a basic example of a class decorator.

Sure! Here's a simple class decorator that logs the creation of a class instance:

function LogClass(target: Function) {
    console.log(`Class ${target.name} is created.`);
}

@LogClass
class MyClass {
    constructor() {
        console.log('MyClass instance created.');
    }
}

This will log a message when MyClass is instantiated.

That's great! Can I use decorators on methods as well?

Absolutely! You can create method decorators to modify the behavior of class methods. Would you like to see an example?
