Why would anyone build with this?

REASON 1

Write property-based tests in Scala that automatically generate hundreds of random inputs to find edge cases.

REASON 2

Combine ScalaTest's organized test structure with ScalaCheck's random generators in a single readable test file.

REASON 3

Run the same test suite on JVM, JavaScript, and Native targets to verify cross-platform correctness.
