If-else condition with Realtime firebase

Please help, I wanted to ask, is it possible to use if/else on firebase's realtime results, which is enter image description here Previously I've tried it and it works if the result of both "waktu" is same, == recent. but what I want is if one of the values "waktu" == recent, then "Hasil" = 0, if both of "time" nothing is equal to "Recent", then the value "Hasil" = 0.

if ("Recent" == (one of) "waktu") {
   Hasil : "1";
} else {
   Hasil : "0";
}

This is my code before, which value "Result" = 1, if both "waktu" values == recent. but i want if one value of "waktu" == Recent.

      var recent = "";
      var root = firebase.database().ref();

      root.child("Time").on('value', (snapshot) => {
        recent = snapshot.val().Recent;
      });

      root.child("jadwal-pakan").on('value', (snapshot) => {
        snapshot.forEach(jadwal_waktu => {
          if (jadwal_waktu.child("waktu").val() == recent) {
            root.update({
              Keadaan: {
                Hasil: 1
              }
            });
          } else {
            root.update({
              Keadaan: {
                Hasil: 0
              }
            });
          }
        })
      })

Thank you :)
