Introduction to Purescript

The talk gives an introduction to Purescript. Purescript is a pure functional language which compiles to Javascript and has support for pretty advanced features that a programmer can expect, like higher kinded types, poly kinded types, row polymorphism, and good type inference. It interops seamlessly with Javascript and can be used to write concise, elegant and expressive code which can run on any JS engine. The ideas used in the language are very similar to Haskell, another pure functional language. It doesn’t have a runtime and the generated JS code is very clear and is easy to look at and debug. Purescript helps prevent a huge class of run time bugs. The type system is very strong and aids type inference and also code suggestion. So it helps manage huge codebases by separating effectful code from pure code and keeps effects at its edges and very minimal.
