Gain a solid understanding of the fundamental concepts of Haskell, a powerful functional programming language, in this introductory course with Alejandro Serrano.
Haskell is an advanced open source language that’s purely functional. It features concise built-in concurrency and parallelism, thousands of libraries, and a rich ecosystem making it a valuable tool for any programmer.
Learn the basic concepts, techniques of this mathematical-based language, change the way you think about programming, and start developing concise programs with increased type safety.
This in-depth course combines virtual classroom lectures and hands-on guided exercises designed to introduce attendees to all the concepts, ideas, techniques, and libraries that they’ll need to start developing their first programs in Haskell.
