 ## Getting Started
 Modern JS applications are divided into 2 types:
-- CSR - Client-Side rendering. The application will be displayed only after downloading and executing all the necessary JS code. Until then, the user will see a blank page. It degrades the UX and is bad for SEO.
-- SSR - Server-Side rendering. The auxiliary server doesn't send a blank page, but a page with data. Thus, the user can immediately start working with the application, and SEO bots will index the page.

 ## Problems
 
-One of the key problems with SSR applications is asynchronous operations. JS is an asynchronous language, all requests to the server, on which our application data depends, are asynchronous. They affect the state of the system - these are side effects. Since content availability is critical for search engines, we must handle this asynchronous behavior. The React Server Renderer is designed as a synchronous operation that steps through our React-DOM step by step and turns it into HTML.

 ## Motivation
 React currently has many solutions for building SSR applications. The most popular solution is **Next.JS**. This is a great framework with many possibilities, iSSR cannot replace it. But, **Next.JS** is about completely rewriting your existing application. **Next.JS** is a framework, which means you have to use its approaches. **iSSR** is just a small library that handles side effects and synchronizes state.
