Now JavaScript frameworks. It's been a full year since npm's survey, so these numbers differ from ours in the directions I expected:
React 65% (vs. 60%)
Vue 29% (vs. 24%)
Ember 5% (vs 4%, I was expecting a bigger rise)
But there's a shocker in here: Angular.

Sneak preview: we're adding support for the wct test runner. Any #Polymer or other #webdevelopers out there using wct excited for #MutationTesting with #strykermutator? Let us know! github.com/stryker-mutator/s…
#Facepalm 🤦♂️moment of the day! Test is failing:
"Expected null to be truthy."
Looking at the assertion:
// TODO: change this assert expect(response).toBeTruthy();
// to:
// expect(response).toBeNull();
// currently it states: expected 'null' to be null.

I just today figured out why #nodejs's `fs.exists` is deprecated. It's callback function doesn't accept an error as first parameter! It breaks nearly every custom `promisify` implementation out there! Be warned! It's a stable api too, so deal with it 😤. nodejs.org/api/fs.html#fs_fs…

#TypeScript 3.1 has been released. They're keeping up the trend of making sure we can improve code with each release! Awesome job by the team. My favorite new feature: Easier properties on function declarations. blogs.msdn.microsoft.com/typ…
