How to call a method of one class in another?

Question

JavaScript

Hello! available Model:

class Model extends EventEmitter {
    constructor() {
    }

    getMethod() {
        console.log()
    }
}

which inherits EventEmitter.
EventEmitter also inherits View:

export default class View extends EventEmitter {
    _model: Model;
    _elements: Elements;

    constructor(model: any, elements: any) {
        super();
        this._model = model;
        this._elements = elements;
    }

    test() {
        console.log(this._model.getMethod());
    }
}

but when calling getMethod on the View in the test method, it says: Property 'getItems' does not exist on type 'Model'.
How to call the getMethod method in another class and what's the problem?
PS The code is not all! described the main points.

Answer 1

If this._model is true an object from Model, then there will be no problems. Your error says something else. It does not mention getMethod, but getItems. Look for the problem elsewhere.
