Not only was my information send perfectly, it IS perfect information 😌! Everyone, please fill in the #stateofjs form here: stateofjs.com/ We use it to make decisions about where to focus on.
Just wait a little longer and we finally have a type safe `apply`, `call` and `bind` in #TypeScript! Yet an other awesome PR by @ahejlsberg
Variadic functions at work. Took us four years to get expressive enough to fix this one! @typescriptlang #TypeScript github.com/Microsoft/TypeScr…

I'm really impressed with TSLint. I learned yesterday that it can fix most issues using `--fix`. Awesome discovery. Resulted in a merged PR with > 500 changed files: github.com/stryker-mutator/s… #TypeScript
Thanks to @InfoSupportBV for remembering that last Saturday was my 10 year anniversary working for the company. Really appreciated 🥇! Man, time truly flies by fast.

In preparation of the 1.0.0 release of Stryker we're renaming some config properties. Starting from stryker-api@0.20 and stryker@0.28.0 the reporter property has been renamed. If you have an existing config, you will get a deprecation warning with info on how to upgrade 👍

I think this is the longest it ever took @dependabot to fix an issue. From reporting to a PR took ~30 minutes. And that even though we pay them €0 ($0). Don't you just love #opensource? /cc @_simondel github.com/stryker-mutator/s…
