React Virtual DOM

Please correct me anywhere if i am wrong.

React has a virtual dom and if anything changes it compares those changes with the new virtual dom and apply those changes in minimal number of steps to the real dom.

So does it has two copies always or with each re-render a new virtual dom is made and it compares with the previous latest one.
