Can you explain the difference between rendering methods: SSR, SSG, CSR, and ISR?

Differences between rendering methods:

• SSR (Server-Side Rendering) — rendering the page on the server for each request. The server generates HTML and sends it to the client. Pros: fast initial render, SEO-friendly. Cons: server load, delay on each request.

• SSG (Static Site Generation) — generating static HTML files at build time. The client receives a ready-made page without additional processing. Pros: high speed, easy scaling. Cons: not suitable for frequently changing content.

• CSR (Client-Side Rendering) — rendering occurs in the browser using JavaScript. The server usually delivers minimal HTML and JS bundles. Pros: interactivity, flexibility. Cons: slow initial render, SEO issues without additional configurations.

• ISR (Incremental Static Regeneration) — a hybrid approach that allows updating static pages after deployment without a full site rebuild. Pages are generated statically but can be updated on a timer or upon request. Pros: combines the advantages of SSG and SSR, suitable for dynamic content with high performance.

Example: Next.js supports all these methods, allowing you to choose the optimal approach for your task.
