Web programming with higher order functions

Question

We study higher-order functions in our class, and our professor noted that they can be useful for web programming. I am not sure what cases in which this would be true, and I wondered if anyone had experience with higher-order functions in some common web programming tasks and in which situations they would be useful.

I read our book, but web programming was not mentioned, I suppose this was what the professor was talking about, but it a little aroused my interest.

Thank!

Answer 3

Clojure makes extensive use of higher-order features for web development in its superior Ring framework . Watch this great video that explains some of the concepts.

Main idea:

• A web application is just a function that displays a response request
• This way you can compose an entire web application using higher order functions.
