    Do you want to use document.write()? It doesn't work.

    Please use console.log() ;-)

    I'm using JS and get that:

    Time: 265ms Passed: 2 Failed: 0 Errors: 1
    Test Results:
    ✔ Test Passed: Value == 0
    ✔ Test Passed: Value == 0
    ReferenceError: document is not defined
    at duplicateCount

    What does it mean?
