Thought this might interest the general programming community as well! If you've ever been interested in the different types of ways websites can render themselves....

Here’s a quick summary of the different ways you can load a website.
SSR (Server Side Rendering): The classic way. Browser makes request to server, server creates an HTML/CSS/JS bundle, sends it to browser.
CSR (Client Side Rendering): The vanilla React way. Browser makes a request to server, server sends back JS code which runs on browser, creating the HTML/CSS and triggering browser to further make requests to load all assets.
SSG (Static Site Generation): The “gotta go fast” way. Server creates an HTML/CSS/JS bundle for web pages at build time. When browser requests a page, the server just sends this pre-built bundle back.
ISG (Incremental Static Generation): The “imma cache stuff” way. Server may create some HTML/CSS/JS bundles for web pages at build time. When the browser requests a page, the server sends this pre-built bundle back. If a pre-built bundle doesn’t exist, it falls back to CSR while it builds the bundle for future requests. The server may auto-rebuild bundles after certain time intervals to support changing content.
ESR (Edge Slice Re-rendering): The “cutting edge, let's get latency down so low it's practically in hell” way. Server does SSG and tells the CDN to cache the bundles. Then, it instructs the CDN to update the bundle in the event that page content needs to change.
In order of performance, usually: (SSG = ISG = ESR) > CSR > SSR
In order of SEO: (SSR = SSG = ISG = ESR) > CSR
In order of correctness (will users be shown “stale” information?): (SSR = CSR) > ESR > ISG > SSG
