ECMAScript differences between ES2022 and ESNext

Question

I'm developing a TypeScript Node.js project with Next.js.

I have noticed that in the TypeScript configuration file tsconfig.json, it allows me to specify the values of the "target" and "label" fields as ES2022 (ECMAScript 2022) and ESNext (ECMAScript Next). Could someone please enlighten me about the significant differences between using ECMAScript 2022 and ECMAScript Next?

Your insightful information would be greatly appreciated.

ES2022: This is the stable version of JS from 2022. It includes features like class fields, top-level await, and some new methods for built-in objects. If you choose ES2022, you'll have stuff that's well-supported and reliable right now.

ESNext: This is living on the cutting edge. It includes the latest features that are in the pipeline for future JavaScript versions. You'll get to play with the newest bells and whistles in JavaScript, but keep in mind that not all environments might support these features yet. You may need polyfills or transpilers to make sure everything works everywhere.

For most production applications, I would suggest ES2022. ESNext for experimentation IMHO
