Julia is a high-level, high-performance programming language for technical computing. It was developed to solve the two-language problem by combining the ease of use of dynamic languages like Python with the speed of compiled languages like C. Julia is designed for numerical and scientific computing, but it is also flexible enough for general-purpose programming. Its key features include just-in-time (JIT) compilation, multiple dispatch, and a rich ecosystem of packages and libraries.
