Approach to Improve Slow React Application Rendering

Slow React Application Rendering may occur due to heavy components, images, bad code practices unnecessary renders due to changes in states. This problem can be reduced by code splitting, avoiding unnecessary re-renders and memoization. We will be using useMemo hook to reduce calculations and updates to improve rendering.

Slow React application rendering as its name suggests is a small or large delay in rendering elements. There may be multiple reasons for that. React uses the concept of Virtual DOM. All the elements in React are rendered using the render method in which we have to provide an id of an element (mostly div) to be rendered. Every element in React is immutable. Hence, to Update the element, we have to call the Render method again.
