Frontend in functional language? Hold my beer!

Vagif is a backend developer like many of you. What should he do when he needs to show some data? Write a program for the console? Or maybe learn CSS and JavaScript? In his daily tasks, Vagif uses F# and functional programming. When he heard about the MVU pattern and the functional approach to user interface development, implemented in the Elm language and transferred to F# by the Fable and Elmish libraries, he decided to try it in his projects.

What did the speaker do? Did he manage to write a normal web application in F#? Come to Vagif's talk and judge for yourself.
