Following is my TypeScript code, which is showing error in Visual Studio Code, let me know what I am missing here -

Code -

class Queue {
  data = [];

  push(item: number) {
    return this.data.push(item); <- red error showing on item  here
  }

  pop() {
    return this.data.shift();
  }
}

const myQueue = new Queue();
console.log(myQueue.push(5)); // Ouptut - 1
console.log(myQueue.push(7)); // Output - 2

Error -

Argument of type 'number' is not assignable to parameter of type 'never'
