ES9 - New Features
Asynchronous iterables cannot be iterated using the traditional for..of loop syntax as they return promises. ES9 introduces the for await of loop to support asynchronous iteration.

[AskJS] How often do you use the ES6+(ES7, ES8, ES9 and ES10) syntax? Do you like it? Does it help?
All the time, as often as possible. Many of the changes are designed to reduce code size and enhance clarity, it'd be absurd not to use them. ?? ?. { ...a } ( ...a ) { } = [ ] = { a = } [ a = ] class () => .findIndex It goes on and on. Can't wait for Temporal. More on reddit.com

Do I need to learn ES7 - ES9?
Yes/No. JS made a lot of modern changes with EMCA2015/ES6+, which you are currently learning. Some of the big changes are arrow functions, let/const, revised scoping, etc. Once you finish what you are learning, you can just look up the new ES7-9 features and learn them, from what I recall the biggest jump is what you are learning now (ie the new changes aren't as drastic). Once you finish this series, you can just check out the differences of the new feature sets via blog posts or documentation. More on reddit.com

The 5 features of ES8 and a wishlist for ES9

My wishlist for es48:

  • blogs add links to spec drafts for further technical information about each proposal

  • blogs explain stuff like async functions in terms of inner mechanics, we all know async/await gonna be cool...

  • blogs are more creative with their content, this is the fifth blog post which lists some proposed es_ feature in a brief summary.

  • I don't have to be such a dick in my comments.

Your wishlist is fine tho.

The 5 most transformative JavaScript features from ES9 - Coding Beauty
May 4, 2024 - Capture groups has always been one of the most invaluable regex features for transforming strings in complex ways. JavaScriptCopied! const str = 'The cat sat on a map'; // $1 -> [a-z] // $2 -> a // $3 -> t // () indicates group str.replace(/([a-z])(a)(t)/g, '$1*$3'); // -> The c*t s*t on a map ยท So normally the groups go by their relative position in the regex: 1, 2, 3โ€ฆ ยท But this made understanding and changing those stupidly long regexes much harder. So ES9 solved this with ?<name> to name capture groups:

Exploring the Exciting New Features in ECMAScript (ES7, ES8, ES9, ES10): Enhancing the Power of JavaScript | by liva jorge | Medium
June 15, 2023 - Asynchronous Iteration: Asynchronous iteration was introduced in ES9 to support working with asynchronous data streams. It enables developers to iterate over asynchronous data sources, such as promises or async generators, using the for-await-of loop. This feature facilitates the handling of asynchronous operations, making code more flexible and scalable. ES10, released in 2019, focused on smaller but valuable additions to JavaScript.

Mobile Application Development is the process through which a mobile app, such as virtual personal aids, digital assistants like virtual, personal, Voice-controlled, Artificial Intelligence, and Conversational Assistants or mobile phones, is created for mobile devices. Such applications can be pre-installed on telephones during mobile application development processes, or supplied with server-side or client-side processing applications (for example, JavaScript), in order to provide an app-like interface within a Web browser.
