Ensure that the parameter signature of one function matches the parameter signature of another function

I have been attempting to implement the following code:

addEventListener(...args: Parameters<EventEmitter>) {
    this.on(args);
  }

Unfortunately, it is not functioning as expected.

The initial error related to

...args: Parameters<EventEmitter>
states that
Rest parameter 'args' implicitly has an 'any[]' type.

As for the second error concerning this.on(args), it reads

Expected 2-3 arguments, but got 1.

I am aware that this.on represents an EventEmitter and I wish to rename it so that I can utilize this.addEventListener on my specific instance.

Answer №1

Success!

  addEventListener(...args: Parameters<EventEmitter['on']>) {
    this.on(...args);
  }

(I finally figured it out)
