How to send data from user registration form to firebase database

Thanks in advance and sorry if this question is asked earlier. I am new to firebase and javascript, here I create a registration form for the user with the following fields:

  • Username
  • Company name
  • Contact No
  • Email address
  • Password

I also studied some lessons and samples, but in these tutorials I found that there were only email fields and a password that were used for authentication, but in my case I also want to register a user to insert a username, email address, company name, contact no in firebase database ...

Can someone help me ... below is my code
