I'm trying to get Firebase data of the last 24 hours. Actually I have this query:
var ref = firebase.database().ref().child("datos").child("pedidos").child("nuevos");
How I can do that?

Reset to default 10use orderByChild method on the timestamp child (or what ever you use store the time ), and startAt to get the data only that before 24 hours
let before24Hour = new Date().getTime() - (24 * 3600 * 1000);
firebase.database().ref().child('datos/pedidos/nuevos').orderByChild('time').startAt(before24Hour).on('value' , function(snap){
console.log(snap.val());
});
