Best Practices for ES6 Promises

ES6 promises are great! They are integral constructs for asynchronous programming in JavaScript, ultimately replacing the old callback-based pattern that was most infamously known for bringing about deeply nested code ("callback hell").

Unfortunately, promises are not exactly the easiest concept to grasp. In this article, I will discuss the best practices I have learned over the years that helped me make the most out of asynchronous JavaScript.

TestCafe is a Node.js tool to automate end-to-end web testing.

Works on all popular environments: TestCafe runs on Windows, MacOS, and Linux. It supports desktop, mobile, remote and cloud browsers (UI or headless).

1 minute to set up: You do not need WebDriver or any other testing software. Install TestCafe with one command, and you are ready to test: npm install -g testcafe

Free and open source: TestCafe is free to use under the MIT license. Plugins provide custom reports, integration with other tools, launching tests from IDE, etc. You can use the plugins made by the GitHub community or make your own.

Bun is a modern JavaScript runtime like Node or Deno. It was built from scratch to focus on three main things:

- Start fast.
- New levels of performance.
- Being a great and complete tool.

Bun is designed as a drop-in replacement for your current JavaScript & TypeScript apps or scripts — on your local computer, server or on the edge. Bun natively implements hundreds of Node.js and Web APIs, including ~90% of Node-API functions (native modules), fs, path, Buffer and more.

The goal of Bun is to run most of the world's JavaScript outside of browsers, bringing performance and complexity enhancements to your future infrastructure, as well as developer productivity through better, simpler tooling.
