Type-driven Programming

One of the greatest strengths of OCaml is its powerful static type system. The OCaml compiler is able to automatically detect a large class of bugs, allowing the developer to fix the problems before releasing a usable software. Programs can be trusted, without losing efficiency. Moreover, the compiler performs a lot of analysis at compile-time, sparing costly checks by the language runtime when the program runs. That is why OCaml programs are highly optimized and can even be faster than equivalent C programs, while being much safer!

Industrial Users
