How can I get the value of the variable 'clickedName' outside the function 'getClickedName()'?

var clickedUidName = firebase.database().ref('users/' + clickedRefUid + '/name');
clickedUidName.on('value', function getClickedName(snapshot) {
  var clickedName = snapshot.val();
  //call your function here
  myfunction(clickedName);
});

function myfunction(clickedName){
   // do something with clickedName
}

Hello again, how can I console.log the 'clickedName' value outside the function? – Unaidu Sep 23 '18 at 16:52
you need to `console.log` in `myfunction`. because this will called after the value to `clickedName` arrived. – Aagam Jain Sep 23 '18 at 16:54
