How to optimize your React JS App Performance?
4 Ways to Optimize your React JS App Performance :
Stop over-rendering
Sometimes react renders more components than it has to, creating problems for developers. For instance, react might continue updating the page even after all the components are updated to the necessary state. This constant updating increases CPU components and decreases speed. The issue isn’t common and hugely impacts user experience. However, you can follow these strategies to solve the problem:
Pure components:
Pure components are a class in react JS that compares the current state and props with the new state and props to determine whether react components should re-render. If the state and props are the same, pure components will restrict the re-rendering of components.
Hooks:
React Hooks are simple JavaScript functions that allow you to separate the reusable part of the functional component. These functions enable you to hook several components and automatically check the code’s status. And this further helps optimize your React app.
Filter out the props
When optimizing component rendering in React JS, you need to ensure that components
receive only essential props. This will help you regulate CPU consumption and prevent
features from unnecessary over-rendering. For this, you have to create a functional
component that collects and redistributes props to other components. The code can be
slightly complicated when you need to handle a lot of props. Still, this method allows you to ensure stability and predictability.
Assess faulty components
When optimizing React App, the first thing to look out for is the components that aren’t
working the way they should. If you have a team of testers and carry out user acceptance
testing, you already know these components.
However, you can also identify these errors without them. If the pages in your app freeze,
it is likely that the components are not working correctly. But even if the page doesn’t
freeze, you should still try connecting the components and increasing the order of magnitude to check how the feature works with each other.
Google Dev Tools and React Dev Tools are great tools for seeing highlights and creating
diagrams with poorly performing components. You will immediately identify issues and be
guided on how to solve them. Mobile App Development Company in Gurgaon is a great source for
solving issues and for development also.

Implement virtualization
Often component performance occurs when there is too much data on the page. eCommerce
websites need to render a lot of data when displaying product cards on the web page in a
single session. But this leads to higher CPU consumption and slower loading speed, resulting
in a bad user experience.
One of the simple solutions to this issue is pagination. With pagination, you can load a
certain number of items on a single page. But this is not an efficient option if the user wants
to see all the items without switching pages. Excessive pagination prevents the website’s
smooth flow.
That’s when virtualization comes into play. The DOMs settings allow you to keep all the items on the page, but first, you only render some of them. Then, other items get rendered
when users scroll down further. This allows you to distribute CPU resources and increase performance.
