Course Summary
ReasonML offers a sound type system which means that programs with incorrect types will be rejected by the compiler so that a program won't get into invalid states. Every line of code is covered by the type system.
This course begins by covering the fundamentals of ReasonML. Next, a number of small applications will be developed by students as they learn about strong type inference, which helps to eliminate time writing type annotations so there is more focus on business logic instead. The course concludes by exploring expressive type features coupled with an extremely fast edit-compile-run feedback loop which increases productivity.
Attendees must have experience in developing in JavaScript for the web. Experience using React will be of benefit but not required.
