What is work in progress tree in react fibre?

Difficulty: 6/10

Fiber architecture, Reconciliation, Commit phase

In Fiber, there are two trees: the current tree and the work-in-progress tree.

1
The current tree represents the component tree that is currently rendered on the screen.
2
The work-in-progress tree is a clone of the current tree, which React uses to perform updates.
3
During the reconciliation process, React updates the work-in-progress tree, compares it with the current tree, and then commits the changes to the DOM.
4
This approach allows React to work on the updates incrementally, without blocking the main thread, and efficiently manage the rendering process.
