"When I use breakpoints and run my application in debugging mode, it performs flawlessly. However, without these tools, it

I have developed an application using the Ionic Framework with Firebase as the backend. When I run the application with breakpoints using the debugger, everything works fine. However, if I run it without the debugger, I notice that values are not being updated in the Firebase database and page transitions are failing. Any insights on why this behavior occurs?

Here is a snippet of my HTML code:

<a class="button button-balanced button-block" id="snooker-button1" ng-click="setTitle('Table 1')" ui-sref="tableX">Table 1</a>
    <a class="button button-balanced button-block" id="snooker-button2" ng-click="setTitle('Table 2')" ui-sref="tableX">Table 2</a>
    <a class="button button-balanced button-block" id="snooker-button3" ng-click="setTitle('Table 3')" ui-sref="tableX">Table 3</a>
    <a class="button button-balanced button-block" id="snooker-button4" ng-click="setTitle('Table 4')" ui-sref="tableX">Table 4</a>
    <a class="button button-assertive button-block" id="snooker-button5" ng-click="setTitle('Table 5')" ui-sref="tableX">Table 5</a>
    <a class="button button-balanced button-block" id="snooker-button6" ng-click="setTitle('Table 6')" ui-sref="tableX">Table 6</a>
    <div class="button-bar">
        <button class="button button-calm button-block button-outline" style="font-weight: 600;" id="page3-button11" ng-click="gameEngine_v()">Start</button>
        <button class="button button-calm button-block button-outline" style="font-weight: 600;" id="page3-button12" ng-click="gameEngine_v_stp()">Stop</button>
    

Below is a portion of my Controller.js file:

$scope.setTitle = function(table_title) {
        // code snippet for setting the title
    }

    $scope.gameEngine_v = function() {
        // code snippet for gameEngine_v function
    }

    $scope.gameEngine_v_stp = function() {
        // code snippet for gameEngine_v_stp function
    }

    var gameEngine = function() {
        // code snippet for gameEngine function
    }

It's been pointed out by David that this issue is likely due to race conditions. The issue with your JavaScript code is that it's not properly handling asynchronous calls. Firebase's dbref.on is an asynchronous call, meaning that the function will only execute once data is received from the server. Therefore, the processing of tables_snapshot and players_at_table_snapshot should be inside their respective asynchronous handler functions. Keeping them outside of these handlers is what's causing the problems.
