Haskell is a statically-typed purely-functional programming language with non-strict evaluation. These features make programming in Haskell quite different from programming in other languages.

This talk will illustrate how to use Haskell for implementing simple 2D animations, firstly using basic functional programming techniques and data types, and then using lenses, for accessing nested data types, and the state monad, for simulating mutable states.

Since the beginning of the language, many interesting tools were implemented for developing in Haskell (REPL, central package archive, property-based testing...). Today, the Haskell tooling provides several powerful and intuitive setups.

This talk will present some useful features provided in a classic modern setup (cabal + HLS + vscode). Some of these features are also widespread in other programming languages, some are more specific to the Haskell world.
