What are the different types of decorators in TypeScript?

In TypeScript, there are three main types of decorators: class decorators, method decorators, and property decorators. Would you like to know more about each type?

Yes, please explain class decorators.

Class decorators are functions that are applied to a class declaration. They can be used to modify or enhance the class. For example, you can add metadata or change the class prototype.

Can you give me an example of a method decorator?

Sure! A method decorator is a function that is applied to a method of a class. It can be used to log method calls or modify the method's behavior. Here's a simple example:

function Log(target: any, propertyName: string, descriptor: PropertyDescriptor) {
    const originalMethod = descriptor.value;
    descriptor.value = function(...args: any[]) {
        console.log(`Calling ${propertyName} with args: ${args}`);
        return originalMethod.apply(this, args);
    };
}
