This rule prevents floating Promises in your codebase. A floating Promise is a Promise that doesn't have any code to handle potential errors. Always make sure to handle promise rejections otherwise yourNode.js server will crash. 13. @typescript-eslint/no-misused-promises ...
For many programs in JavaScript, code is executed as the developer writes it—line by line. This is calledsynchronous execution, because the lines are executed one after the other, in the order they were written. However, not every instruction you give to the computer needs to be attended t...
The await keyword is only valid inside async functions within regular JavaScript code. Note:Async functions always return a promise. If the return value of an async function is not explicitly a promise, it is automatically wrapped in a promise. JS async/await simple example The following is a ...
Windows Runtime and Windows Library for JavaScript provide a way to overcome these problems by implementing theCommon JS Promises/Aproposal. A promise object returns a value at some time in the future. You can use these objects to construct chains of asynchronous code that are easier to read....
Dependent and Independent Code Callback functions are the basic building block of asynchronous event-driven programming in Node.js. They are functions passed as an argument to an asynchronous I/O operation. They are called once the operation is finished. Callback functions are the implementation of...

In this brief post we talked about the tricks and techniques we can use to write simpler and shorter asynchronous code. The beauty of Node.JS platform is that there are multiple ways to achieve this simplicity. And a lot of it also comes from the new syntax introduced by EcmaScript 2015+...

This is why code shaped this way is called theObserver Pattern, which is better represented by theaddEventListenerinterface in this case. Soon event emitters libraries or frameworks exposing this pattern flourished. Node.js And Event Emitters
It is compatible withTaskJS, a library by Dave Herman of Mozilla that uses ES6 generators to allow you to write synchronous code with promises. It currently works in Firefox, and will work in any browser that adds support for ES6 generators. See the section below on TaskJS for more informat...
