A well-liked JavaScript package for creating user interfaces is called React. React JS 
development company uses it extensively to create web apps with great performance. 
However, maintaining the performance of these apps can become difficult as their 
complexity rises. We'll go over the best React performance optimization strategies for 
2023 in this blog post, which will help you make your web apps run faster and more 
effectively.
There are various advantages to using the React framework. However, one of the 
biggest worries among developers is the performance problems with ReactJS 
development company projects. To provide you with tips on how to boost the 
performance of your React project, we have put together some extremely useful 
information. 
How can react performance boost your business?
There are some points which can prove that react JS web development services are very 
important to hype your business.
 Component hierarchy- React apps are constructed from components that hierarchically 
arrange themselves. Components are reusable user interface elements that might be 
functional or class-based.
 React's virtual DOM- A virtual DOM, a condensed replica of the browser DOM, is used by 
React. React js web development services can maintain and update the UI more effectively 
thanks to the Virtual DOM.
 Initial render- React builds the initial Virtual DOM tree based on the component hierarchy 
when a React application loads. 
 Reconciliation and diffing- React's reconciliation process is triggered by modifications made 
to the props or application state after the first render. React JS development company uses 
a diffing mechanism to compare the old and new Virtual DOMs.
Now let's discuss 14 React Performance Optimization 
Techniques for 2024
1. React Memo
Re-rendering the React components might cause the apps to run slowly and the user 
interface to become sluggish. It also detracts from the user experience. Therefore, it is 
essential to reduce unneeded renders to avoid such problems a company should be in 
contact with reactjs web development services.
2. Lazy loading images
Most programmes contain images. Avoid rendering every image at once if you wish to 
optimise an application with multiple images. It can significantly improve how quickly a 
page loads. 
With the help of a React JS development company using lazy loading, you may delay 
rendering the images in the DOM until after they show up in the viewport. It aids in 
stopping the formation of extraneous DOM nodes. It significantly improves the 
performance of React apps.
3. Reselection
Without a doubt, Redux and React function well together. Redux, however, frequently 
results in performance problems. The primary cause is needless re-rendering when the 
state varies. 
Reselect aids memoized selector construction. Only when there are any modifications to 
the data can re-rendering be permitted by the memoized selectors. Consequently, it 
improves React apps' performance. 
4. Server-side rendering
React js development company may efficiently solve performance issues and search engine 
optimisation with server-side rendering. It can produce static content in the browser 
before sending it to the user's browser. 
Site loading speeds can be increased with the use of server-side rendering. The user sees a 
preview of the finished page, however, it will take some time to load.
5. Immutable data structure
Understanding immutable data structures is simple. The main concept is to refrain from 
directly altering an object made up of intricate data. You should hire a React JS 
development company which helps you to consider duplicating the object with the 
updated modifications instead.
It makes it easy to compare the new object with the original and see the changes. It has 
triggered a UI update so it becomes straightforward. 
6. Code splitting in React
Code splitting is another useful technique for improving React apps' performance. When a 
React js web development services application is rendered, the full application code is 
loaded into a bundle file by default. Bundling can reduce a page's ability to process HTTP 
requests, notwithstanding its usefulness. 
7. Use SETSTATE Function
React app performance can also be enhanced by using the SETSTATE function. In React, 
each component has a state that corresponds to it. A component's state may alter as a 
result of an event that the systems cause or in reaction to user activities.
8. Memoizing react components
Memoization is a perfect optimization technique that includes retrieving the cached 
results, storing the results in memory, and caching a component-rendered operation. The 
memoized component will automatically compare a prop that is received by a child 
component.
9. Windowing and List virtualization
Rendering many rows of items in an application is sometimes necessary. In some 
situations, the objects might or might not show up in the browser's viewport. They are 
rendered in the DOM, though. 
React js development company provides applications whose performance is frequently 
impacted by it, this is where the idea of windowing comes in handy. Only the content that 
is accessible to users may be rendered to the DOM. 
10. React Fragments
React js web development services help wrap or group several components efficiently 
without adding new nodes to the DOM. Rendering several components or child elements 
inside of a single-parent component is advantageous. 
It facilitates the removal of pointless div usage from the programs. This may contribute to 
improving the React apps' speed and functionality.
11. Trim javascript bundles
Auditing and trimming JavaScript bundles is essential if you want to reduce code 
redundancy. Your React application may have multiple redundant and superfluous lines of 
code. Thus React js development company helps to analyse and remove all of these scripts, 
which can aid in enhancing the application's performance. Ensure that the bundled codes 
are appropriately analysed and determined.
12. CSS animation usage
Your React applications need animations if you want to provide a satisfying user 
experience. On the other hand, there are other approaches to using web animations. The 
most well-liked ones are the JS and CSS animations. 
13. Throttling & Debouncing Event Action
The number of times the event handlers are called within a given amount of time is 
referred to as the trigger rate. Application crashes may occur from higher event trigger 
rates. As a result, event-triggering optimization is crucial and this part is to be done with 
the help of a React js development company.
14. Dependency optimization
Optimising the size of the React bundle is another well-liked technique for guaranteeing 
good React performance. Fortunately, there are numerous approaches to reduce the 
bundle size. The most popular techniques include compression, minification, code splitting, 
and lazy loading. Additionally, you can optimise the size of the React package by utilising 
fewer libraries. 
Conclusion
In conclusion, it is impossible to exaggerate the significance of React performance 
optimization in 2024. Improving your React js web development services provide 
application's speed becomes crucial as people expect faster and more responsive 
experiences and web applications get more sophisticated.
