New blog post! After lots of procrastination and vacation vibes, I wrote about the hidden dangers when using JSON.stringify in Node.js. We accidentally stumbled upon this in a debugging process and I thought it was worth sharing. Enjoy!

Interesting:
Meta created React Native. It’s used (with components at least) in their flagship apps: Facebook (iOS, Android), Instagram (Meta Quest), Messenger (desktop).
Google created Flutter. And yet none of their flagship apps use it (Gmail, YouTube, Maps, Calendar).

When software inevitably grows it becomes hard to keep a quality overview. Which code needs urgent refactoring, which code is complex but only known by one author, which code cannot be modified in isolation?

i bitch about it a lot but React Native is awesome. if you’re a native engineer you might feel skeptical, but it isn’t a lowest common denominator crossplatform abstraction. rather, i like to think of it as a scripting orchestration layer for platform views (which you can still write). like in games
