How to get the corresponding firebase doc in javascript?

Question

So far I'm able to retrieve every document in a specific collection, but how do I retrieve specific documents in a single collection? Let's say I have a form, and when the user submits the form a new document is created, I now need to retrieve that SPECIFIC document. How do I do that?

I guess you are looking for this
```
var docRef = db.collection ("collection name").doc("doc name"); =
docRef.get(). then ((doc) => {
if (doc.exists) { console.log("Document data:", doc.data());
} else {
// doc.data() will be undefined in this cas console.log("No such document! ");
}
}).catch((error] => {
console.log("Error getting document:", error);
})
```
