What’s new in ECMAScript 2022, Chrome 103, Edge 103, Polypane 9.1, TypeScript 4.8 Beta, and more | Front End News #070

NOTE: This is issue #070 of my newsletter, which went live on Monday, June 27th. If you find this information useful and interesting and you want to receive future issues as they are published, ahead of everyone else, I invite you to join the subscriber list at

We have a lot of interesting topics this week. First, is the official approval of ECMAScript 2022. Stack Overflow published the results for the 2022 Developer Survey. And we find out how GitHub deals with browsers, old and new.

There are many browser releases as well. Chrome and Microsoft Edge rolled out their 103 update. Polypane 9.1 is now available. And you can give Safari Technology Preview 147 a try to test most of the new features from Safari 16.

The Software Updates of the week include ESLint 8.18, TypeScript 4.8 Beta, Vue 2.7 Beta, and more. And I handpicked a nice set of icons, tools, and generators in the Resources section.

What’s new in ECMAScript 2022

ECMAScript 2022 is now officially a standard. Dr. Axel Rauschmayer tells us what's new in this update:

  • New members of classes
  • Private slot checks via the in operator
  • Top-level await in modules
  • Find the cause of an error with error.cause
  • Method .at() of indexable values
  • RegExp match indices
  • Object.hasOwn(obj, propKey)

More info on all this can be found in the article below:

Stack Overflow 2022 Developer Survey

Each year Stack Overflow takes the pulse of the developer community. This year over 70000 developers answered the survey. Here are some of the highlights:

  • More people learned how to code online (from 60% to 70% year over year)
  • Docker is a fundamental tool for developers (from 55% to 69%)
  • React.js is the most wanted web framework (fifth year)
  • Angular.js is the most dreaded one (third year).
  • 85% of developers say their organizations are at least partially remote.

As all this is just scratching the surface, I invite you to check the full report.

Browser news

GitHub published an article describing their approach to browser support, some usage patterns, and how they deal with older browsers.


Chrome 103 rolled out last week. Here are the important changes that come with this update.

  • Help your browser preload resources before page load with the new HTTP 103 status code
  • Query fonts installed locally with the Local Font Access API
  • Timeouts are now easier with AbortSignal.timeout()

More details on each feature can be found in the release notes:


Microsoft Edge also released the 103 update. Their release notes are the usual obscure ones, but here are the main features I was able to extract:

  • Ability to control automatic profile switching.
  • Clear the remembered certificate and resurface the certificate picker with the Client Certificate Switcher.
  • More reliable web defense with the rewritten Microsoft Defender SmartScreen library

More details on each feature can be found in the release notes:


There is a new version from Polypane as well. Update 9.1 brings Chromium 102, form autofilling, fast overview screenshot, outline panel overlays, and a lot more.


Safari Technology Preview 147 is out and includes many of the new Safari 16 features: Live Text, Web Technologies updates, Web Push, Passkeys, and more.
