A typescript code that represents a queue. You must fix the queue code. The main queue code (all the other files are just using this code) import { Message } from "./Database"; export class Queue { private messages: Message[] constructor() { this.messages = [] } Enqueue = (message: Message) => { this.messages.push(message) } Dequeue = (workerId: number): Message | undefined => { return this.messages.splice(0,1)[0] } Confirm = (workerId: number, messageId: string) => { // This method was empty in the original version } Size = () => { return this.messages.length } }
