Your solution to Array Buffers passed!

Here's the official solution is if you want to compare notes:

────────────────────────────────────────────────────────────────────────────────

    var num = +process.argv[2]
    var ui32 = new Uint32Array(1)
    ui32[0] = num
    var ui16 = new Uint16Array(ui32.buffer)
    console.log(JSON.stringify(ui16))
