    var Tiga = 3;

    var benar = Tujuh > Tiga;
    var salah = Tujuh < Tiga;

    var hasil = benar && salah;
    document.write(`${benar} && ${salah} = ${hasil}<br/>`);//Output operator && (and): true && false = false
    var hasil = benar || salah;
    document.write(`${benar} || ${salah} = ${hasil}<br/>`);//Output operator || (or): true || false = true       
    var hasil = !benar;
    document.write(`!${benar} = ${hasil}<br/>`);//operator Output ! (not) : !true = false

</script>
