Comprehensive Tutorial for Next.js vs React 🔥🔥👌

[Peter Vivo]

SSR rendering speed are depend the server performance, so that is not every time best option, if many user open same webapp then SSR time are increasing.

I also have a bad real life experience with Next.js when we try manage our app parts to include as react nodejs module. But at the end the dependency ageing are caused problem.

In other perspective I was transforming my react app to nextjs and that process working fine.

My current question is: Which is better: TS or jsdoc ( Nextjs are written in TS ).

In current company we are using pure JS-React with node.js backend for SSR. That way also usable, and don't have too much differences between nodejs+React vs Next.js.
