JavaScript Promise: Methods Comparison
Introduction
Promises in JavaScript are used to handle asynchronous operations by keeping track of whether a certain event has happened. If that certain event has taken place, it determines what happens next. Promises return a value which is either a resolved value or a reason why itâs rejected. They can handle multiple asynchronous operations easily and they provide better error handling than callbacks and events.
Callback: A callback is a function that is passed into another function as an argument to be executed later.
Events: Events provide a dynamic interface to a WebPage and are connected to elements in the Document Object Model(DOM), for example: onclick(), onmouseover() etc.
A Promise has four states
Pending: Before the event has happened, the promise is in the pending state.
Settled: Once the event has happened it is then in the settled state.
Fulfilled: Action related to the promise has succeeded.
Rejected: Action related to the promise has failed.

Now Learn JavaScript Programming Language With Microsoft
icrosoft has released a new series of video tutorials on YouTube for novice programmers to get a hands-on renowned programming language â JavaScript.
This isnât the first attempt by Microsoft to come up with video tutorials by beginner programmers. The company also has a series of YouTube tutorials on Python for beginners.
For JavaScript, Microsoft has launched a series of 51 videos as âBeginnerâs Series to JavaScript,â for young programmers, developers and coders who are interested in building browser applications using JavaScript. These video tutorials will also help programmers and coders to use relevant software development kits (SDKs) and JavaScript frameworks, such as Googleâs Angular.
âLearning a new framework or development environment is made even more difficult when you donât know the programming language,â stated on the Microsoft Developer channel on YouTube. âFortunately, weâre here to help! Weâve created this series of videos to focus on the core concepts of JavaScript.â
It further stated â while the tutorials donât cover every aspect of JavaScript, it indeed will help in building a foundation from which one can continue to grow. By the end of this series, Microsoft claims that the novice programmers will be able to work through tutorials, quick starts, books, and other resources, continuing to grow on their own.
