Deep dives
The Role of the Virtual DOM
The virtual DOM is a method of changing UIs by using a small child (the virtual DOM) that communicates changes to the adult (the actual DOM). It works by comparing snapshots of the UI and making necessary changes. While some misconceptions claim that the virtual DOM is always faster or slower than the DOM, the reality is that it depends on specific cases. The virtual DOM excels in handling structural changes but is less efficient in value-based updates.
