Relate IDs with JavaScript

I need help with javaScript (I'm a beginner in programming). I have a list of players registered in the firebase and I need to connect each player with their respective time of proof. A player has id = player1 and has a time with id = timePlayer1 and so goes up to player8 / timePlayer8 and I need to list in order of time and for this I compare the value of each time, but it has to appear the time and the player of that time. follow the code I have here:

<form class="corrida" id="corrida">
                <h5 class="center">Nova Corrida</h5>
                <div class="row">
