Mozilla launches a new Developer YouTube Channel, TypeScript 3.7 Beta and Faster V8 regular expressions | Front End News #21

Hello everyone and welcome to another (very short) round of Front-End News. This has been my first week at my new full-time job in an office after two years of remote work and freelancing from the comfort of my home. As you can imagine, this is wreaking havoc with my available time and energy levels.

Long story short, here are the main events that happened over the last week. Enjoy!

Presenting the Mozilla Developer YouTube Channel

Mozilla Developer YouTube Channel cover

Mozilla started a brand new YouTube channel dedicated to developers everywhere. You will be able to find short videos, articles, demos, and tools that teach web technologies and standards, browser tools, compatibility, and more. There are already a fair number of videos uploaded, with more expected to arrive soon.

What's coming in TypeScript 3.7 Beta

We are getting a sneak peek at the new features coming with TypeScript 3.7 Beta thanks to an article published by the development team. Here is a quick listing of what to expect:

  • optional chaining
  • nullish coalescing
  • assertion functions
  • better support for never-returning functions
  • recursive type aliases

and a lot more things that you can find in the article linked below.

Improving V8 regular expressions

The V8 team made some great progress in improving the execution of regular expressions. I can frankly admit that most of the technical details are way above my level of understanding. But if you are deeply interested in the ways browser engines work, this can be a very interesting lecture.

Software updates and releases

This week I am highlighting updates for a bunch of software packages. In each case, you can find the full details in the release notes linked down below.

Safari Technology Preview 93

NuxtJS v2.10.0

Next.js v9.0.7

Node-RED v1.0

Preact X

That’s all there is in this edition. Follow Front End Nexus on Twitter at to be notified as soon as a new update happens. I also want to encourage you to subscribe to the YouTube channel at I can unlock some more options once the channel hits 100 subscribers, so your support is highly appreciated.

Have a great and productive week and I will see you next time!
