const chunk = Chunk.make(1, 2, 3, 4, 5, 6)
const [before, after] = Chunk.splitAt(chunk, 3)
console.log(Chunk.toArray(before)) // [1, 2, 3]
console.log(Chunk.toArray(after)) // [4, 5, 6]

// Split at index 0
const [empty, all] = Chunk.splitAt(chunk, 0)
console.log(Chunk.toArray(empty)) // []
console.log(Chunk.toArray(all)) // [1, 2, 3, 4, 5, 6]

// Split beyond length
const [allElements, empty2] = Chunk.splitAt(chunk, 10)
console.log(Chunk.toArray(allElements)) // [1, 2, 3, 4, 5, 6]
console.log(Chunk.toArray(empty2)) // []
