Got a question in one of the interviews about how does HTML page load, as in, how the resources are actually being fetched from top to bottom and their execution?
Starting a thread about it here.

Not all resources in the HTML are blocking.
For example, CSS and other static assets are non-blocking.
However, JavaScript is blocking unless it's used with async or defer.

This whole process is all about two things, "Fetching" and "Parsing".
The browser fetches the resource first and then start the parsing.
However, fetching and parsing happens in parallel for multiple resources.
