How does bluebird.join work?

bluebird.join is a method in the Bluebird library for combining the results of multiple promises into a single promise, with the results returned in the order they were passed in as an array.

The first argument of the join method is an array of promises that need to be resolved, and the second argument is a callback function that accepts the resolved values of the promises as arguments and returns the value for the new promise. If any of the promises passed to the join method are rejected, the resulting promise will also be rejected.

const Promise = require("bluebird");

const getUserDetails = (userId) => {
  // simulate a database call that returns user details
  return Promise.delay(1000).then(() => {
    return {
      id: userId,
      name: "John",
      age: 30,
      city: "New York",
    };
  });
};

const getOrders = (userId) => {
  // simulate a database call that returns user orders
  return Promise.delay(500).then(() => {
    return [
      { id: 1, user_id: userId, amount: 10 },
      { id: 2, user_id: userId, amount: 20 },
      { id: 3, user_id: userId, amount: 30 },
    ];
  });
};

Promise.join(getUserDetails(123), getOrders(123), (userDetails, orders) => {
  console.log("User details:", userDetails);
  console.log("Orders:", orders);
});

In this example, getUserDetails and getOrders are two functions that return promises. We use Promise.join to execute these functions in parallel and get their results. When both promises are resolved, the then callback is called with the results of both promises.
