What is reconciliation?
- The process of comparing two versions of a component and updating the DOM with the changes
- The process of defining the structure and behavior of a component
- The process of rendering a component to the DOM
- The process of testing a component for bugs and errors
Reconciliation is the process of comparing two versions of a component and updating the DOM with the changes. When a component's state or props change, React compares the new version of the component to the previous version and calculates the minimum number of changes needed to update the DOM. This process is called reconciliation and is one of the key features of React that makes it so efficient.
