Type-related failures are common and can be very costly. Famously, in 1999, NASA's Mars Climate Orbiter burned up in the atmosphere because of an error that could have easily been prevented with typing. By taking advantage of the strong type systems available in most modern programming languages, you can eliminate whole classes of errors.

Programming with Types teaches you type system techniques for writing software that's safe, correct, easy to test and maintain, and that practically documents itself. Master these techniques, and you may even help prevent an interstellar catastrophe!

About the technology

As software grows in complexity, it's essential to adopt coding tools and strategies that enforce safety and correctness. A type system governs what types of data are allowable, requiring your code to accurately store, represent, and use its internal data.
