Some basic TS utils for personal use

import { EventEmitter } from "events";
export class EventBus extends EventEmitter {
    constructor() {
        super();
    }
    static getInstance() {
        if (!EventBus.instance) {
            EventBus.instance = new EventBus();
        }
        return EventBus.instance;
    }
    subscribe(eventName, callback) {
        this.on(eventName, callback);
    }
    unsubscribe(eventName, callback) {
        this.removeListener(eventName, callback);
    }
    publish(eventName, data) {
        this.emit(eventName, data);
