How to fetch all data from firebase

Question

I connected firebase database with my code and tried to fetch data. But it only fetches the last data.

Here, it only fetches the last name and email id. But I want to fetch all names and email ids and write these in innerHTML like
Name 1
Email 1
Name2
Email 2
Name3
Email 3
How can I do that ?😢

How ?
I have 18+ emails and names in my db. But it only shows the last one in innerHTML. (Although all are shown in console)
