create a queue for chaining async methods in javascript

To create a queue for chaining async methods in JavaScript, you can use the Promise API along with a custom implementation of a queue. Here's an example implementation:

index.tsx
class AsyncQueue {
  constructor() {
    this.queue = Promise.resolve();
  }

  add(asyncFn) {
    this.queue = this.queue.then(asyncFn);
    return this;
  }
}

In this implementation, AsyncQueue is a class that represents a queue of asynchronous functions. The add method adds a new function to the end of the queue and returns the queue itself for chaining.

To use this queue, you can create an instance of it and then add your async methods:

index.tsx
const queue = new AsyncQueue();

queue
  .add(async () => {
    // do some async work
  })
  .add(async () => {
    // do some more async work
  })
  .add(async () => {
    // do even more async work
  });

In this example, each async method is added to the end of the queue, but won't execute until all previous methods have completed. This allows you to chain asynchronous operations together in a controlled way.

Note that this is just one possible implementation of a queue for chaining async methods. Depending on your specific requirements, you may need to modify or extend this implementation to suit your needs.
