Every website or online application has a server side and a client side that are constructed differently, ranging from a simple one-page landing page to an intricate multi-page service. React JS is what we use on the client side. We can create user-friendly web applications with great performance rates thanks to this reliable technology. We have continued to use this technology and expand our knowledge of React JS development services since 2016, when we became a React development firm. Let’s investigate the main points. Because React JS allows server-side rendering, it offers chances for improved search engine optimization for websites and web apps. The technique known as SSR renders application pages on the server side. In this manner, the material gets indexed by search engines more quickly, improving search ranking and ultimately driving more traffic to the online application.
