import { test, fc } from '@fast-check/vitest'
    test.prop([fc.array(fc.double())])('sort is correct', (lst) => {
      expect(lst).toEqual(lst.toSorted())
    })

Was already familiar with and using Hypothesis in Python so went in search of something with similar nice ergonomics. Am happy with fast-check in that regard.
