Julia
/ˈdʒuːliə/
noun … “a high-level, high-performance programming language designed for technical computing.”
Julia is a dynamic programming language that combines the ease of scripting languages with the speed of compiled languages.

Julia achieves this balance through just-in-time (JIT) compilation, multiple dispatch, and type inference.
