I am just starting to explore firebase and I'm having trouble organizing my data. I've attempted to use the query function and orderBy

After experimenting with query and orderBy() methods, I'm still struggling to properly integrate it into my code. Here's what I have so far:

Methods:

async saveMessage(){
  try {
    const docRef = await addDoc(collection(db, "chat"), {
      message:this.message,
      createdAt: new Date()
    });
    console.log("Document written with ID: ", docRef.id);
  } catch (e) {
    console.error("Error adding document: ", e);
  }
  this.message= null;
},

async fetchMessages(){

    const querySnapshot = await getDocs(collection(db,"chat"));
     let allMessages = [];
    querySnapshot.forEach((doc) =>{
      allMessages.push(doc.data());
    })
    this.messages = allMessages;
  }
},

When organizing your results, remember to include an ordering clause in your query:

import { query, orderBy, ... } from "firebase/firestore";  

const querySnapshot = await getDocs(query(collection(db,"chat"), orderBy("name")));

If you want more information on how to efficiently order and limit data using Firebase, I suggest checking out their documentation on ordering and limiting data. This is where I found the modifications for your code.
