Ada vs Haskell

Ada is a statically typed, structured programming language designed for safety-critical and high-integrity systems. Developed originally for the U.S. Department of Defense, it is widely used in aerospace, defense, avionics, and embedded systems. AdaCore provides the primary commercial toolchain (GNAT Pro) along with static and dynamic analysis suites.

Haskell is a languages tool that purely functional programming language with strong static typing and lazy evaluation, influential in programming language research. It is open source software.
