I suggest simply having a look at the table of contents of

This in my opinion gives you a first rough idea for what kind of problems people are using F*.

Spoiler alert: these are not the kind of problems which are related to ["HTTP server", "hello world", "todo list app", ...].

This is exactly the reason why I wrote further above:

> Often the reason [why more languages don't have a few simple examples of: "HTTP server", "hello world", "todo list app"] is that the value that the programming language brings is thinking very differently about how to write code - the examples how to write something in it are merely the "more boring" consequences of this different way of thinking.
