If you are stuck on 16 because of the 100x perf regression/memory leak of vm.Script compilation (or just Jest users getting stuck on 16 due to perf reasons/memory leak), the fix/workaround is in 20 now (v18 backport is WIP)
New Node.js v20.10.0 'Iron' (LTS) release up now ⚡💚

If you are using Jest 25+ in a mid/large repo, could you run:
* `jest --coverage --coverage-provider=v8`
* `jest --coverage --coverage-provider=babel`
and share both coverage results for "All files"?

So happy for this be a part of Sandpack directly! 🎉
Big shout out to @danilowoz for his hard work to help make this a reality!
Oh and collaborating with @codesandbox projects is insanely good! 🤯🙌🚀
SandpackTests allows you to easily run Jest tests on your website, with some cool options such as verbose and watch mode - but you can also run a single suite test.
A huge thanks to @mattphillipsio for the hard work on implementing this component!

This process has taken about a year from the first exploratory conversations. Super stoked it's finally done!

The @fbjest team been working with @opencollect to start a fund supporting Ukraine charities, so far we’re raised over $21,000 dollars! Thanks @BenJam
If you have an Open Collective which isn’t being used, this could be a useful outlet for the donations
opencollective.com/opensourc…
ALT Today we're launching a fund to centralise support from within Open Source Collective for a number of humanitarian and journalistic integrity initiatives concerning the ongoing conflict in Ukraine. Open Source Collective exists to promote a sustainable and healthy ecosystem to sustain open source technology for the future. We believe that the current conflict in Ukraine threatens our ecosystem and we encourage Collectives hosted by Open Source Collective to contribute to support humanitarian and journalistic integrity initiatives. This fund simplifies the process of donating to these initiatives from your Collective — simply select your Collective in the 'Contribute As' step, you will need to be an administrator of a collective to do this. Note that donations to the fund from individuals will be rejected.
