Performance
There are various factors and aspects which are used to improve performance in React which ensure efficient rendering, smooth user interactions, and minimal resource consumption. Some of the key strategies to enhance React app performance:
A. Virtual DOM: React uses Virtual DOM which helps to increase performance of the application. Every time the state of our application changes, the virtual DOM gets updated instead of the real DOM.
B. State and Props Management: Use state effectively and avoid unnecessary re-renders by only updating state when needed. Avoid passing excessive or unnecessary props down the component tree to prevent unnecessary re-rendering of components.
C. Lazy Loading: It refers to a technique which is used to increase performance by loadingcomponenets or assets only whenever required rather than loading everything at a time.
D. Memoization: Use memoization techniques (e.g., useMemo, useCallback) to cache computations and to prevent recalculation of values on each render.
Essential things to know as React Developer
React is an open-source JavaScript library used to create user interfaces in a declarative and efficient way. It is a component-based front-end library responsible only for the view layer of a Model View Controller(MVC) architecture. React is used to create modular user interfaces and promotes the development of reusable UI components that display dynamic data. This article covers all the essential topics provided by ReactJS which every developer should know.
