I had a great time with colleagues, students and friends! We managed to get a lot done for some great open source projects. I will write a blog post about it when I have some time. ❤️
Also: loved the drinks with everyone in the hotel afterwards 😉 🍻
During this #Hacktoberfest Hackathon by Info Support 7 teams were working on #StrykerJS #StrykerDotNet #TypeScript #Maven #ApacheMaven #EntityFramework #Swagger #EFCore #TailwindCSS #GithubActions #Github. What a fest it was!

Hey. That's me 😊
Heb je al kennisgemaakt met @_nicojs? Hij geeft diverse trainingen binnen Info Support en organiseert het Hacktoberfest op 28-29 oktober in Veenendaal/remote. Hij stelt zichzelf graag voor in onderstaand filmpje.

This is exactly what I've been thinking. Better to split type checking and emitting in your workflow.
Didn't know Deno abandoned this approach. Time to take another look 🐉
I have spent the last 4 years living with integrating tsc into Deno. I have also seen a few attempts to re-implement tsc in "3 months" or "2 months". There is often fast progress initially and then comes the long tail of slow or no progress.

Good news everyone! Our website blog now has a comment section powered by #giscus, backed by GitHub discussions. That means you can now discuss awesome new Stryker features right below the blog post 👇. See it in action here: stryker-mutator.io/blog/anno…

I'm learning from @_nicojs that 100% test coverage doesn't necessarily mean you have good tests.

For those who don't know what mutation testing is, you are in luck as I will be having @_nicojs teach mutation testing with StrykerJS tomorrow.

TypeScript 4.9 Beta is now available! Try out our improved 'in' operator narrowing, the new 'satisfies' operator, stricter 'NaN' checks, and more-efficient file-watching defaults!
