What are Salt Rounds and how are Salts stored in Bcrypt?

Question

I am trying to configure Bcrypt for the node application that I am creating and I have a few questions about salts, which I hope someone here can help to kindly answer.

• What is salt? For example, in github docs ( https://github.com/kelektiv/node.bcrypt.js/ ) it uses salt round 10. What does that mean?

• Is the salt generated by Bcrypt always the same? For example, if I save user hashed passwords in the database, is it salt that she used the same password for the hash for each password?

• How is salt stored? Is it safe from potential attacks?
