Optimizing UI Updates for Performance
Introduction
React is known for its efficient rendering process, and one of the key techniques it utilizes is batching. Batching refers to the process of combining multiple
updates into a single update, minimizing the number of times the real DOM needs to be updated. In this article, we will explore how batching works under the
hood in React and its impact on performance. We will also provide examples to demonstrate the concept.
Understanding Batching
When React renders a component, it doesn’t immediately apply every change to the real DOM. Instead, it batches the updates together and performs them all at
once, resulting in better performance and a smoother user experience. React achieves batching through a technique called “transaction,” which groups related
operations and executes them as a single unit of work.
Example: Updating State with Batching:
Let’s consider an example where a component updates its state multiple times in quick succession.…
