QuickCheck Tutorial Part 3 is out! This final part looks at what happens after a property fails — how QuickCheck shrinks a failing sample, and how to tell whether the final counterexample actually explains the bug. Read it here: www.moonbitlang.com/pearls/quick...

Part 2 of our QuickCheck tutorial is out. This time we look at one of the hardest parts of property-based testing: constrained random generation — when valid inputs are rare and simple generators stop working. Full Write-up: moonbitlang.com/pearls/quick...

Most GC'd languages (Python, JS) make FFI painful. MoonBit doesn't. With lifetime annotations (`#borrow`/`#owned`), MoonBit interops cleanly with almost any C memory pattern — making it surprisingly easy to bind to system APIs, native libraries, game engines, you name it. Even stackful coroutines:

MoonBit @moonbitlang.bsky.social · 05/03/2026

Really like MoonBit’s is expression. Destructuring + guards in one line, reducing boundary checks without unsafe operations

MoonBit @moonbitlang.bsky.social · 04/03/2026

AI refactors better with guidance. `moon ide analyze` shows real API usage, so agents can tighten internal package APIs instead of guessing. Less AI slop, cleaner boundaries, better MoonBit code. ⚠️This is available on MoonBit nightly for now, and will be in the next stable
