    Promises in Node.js represent the eventual completion or failure of an asynchronous operation and its resulting value. They are an alternative to callback functions for asynchronous code execution. A promise in Node.js is an object that may produce a single value in the future: either a resolved value or a reason that it's not resolved (e.g., a network error occurred).

    Code Example

    Here's a basic example of creating a promise in Node.js:

    let promise = new Promise(function(resolve, reject) {
    // "Producing Code" (May take some time)

    let isSuccessful = true; // just for demonstration

    if (isSuccessful) {
    resolve('The operation was successful.');
    } else {
    reject('The operation failed.');
    }
    });

    // "Consuming Code" (Must wait for a fulfilled Promise)
    promise.then(
    function(value) { console.log(value); }, // code if successful
    function(error) { console.log(error); } // code if some error
    );

    What is a promise in Node JS?
    The Promise class has been included in Node.js since v4.0.0. That means, unless you're on an unmaintained version of Node.js, you can use promises without any outside libraries. A promise is an object representation of a value that is being computed asynchronously. The easiest way to create a promise is using the Promise.resolve() function.

    Why should I remove a promise from a core Node JS?
    The cool thing about promises is you can combine them into dependency chains (do Promise C only when Promise A and Promise B complete). By removing them from the core node.js, it created possibility of building up modules with different implementations of promises that can sit on top of the core.

    What happens when a promise is fulfilled in Node JS?
    In Node JS, a promise gets resolved during fulfillment and rejected otherwise. These design patterns help eliminate the need for unintuitive callbacks. To summarize, a promise is in one of the three states: resolved. Note: Once a promise is resolved or rejected, its state cannot change.
