Julia is a high-level, high-performance dynamic programming language designed for numerical and scientific computing, data science, machine learning, and other technical computing applications. Julia was developed by a team of programmers led by Stefan Karpinski, Jeff Bezanson, and Viral Shah, and was first released in 2012. One of the key features of Julia is its speed. Julia is designed to be fast, with performance comparable to traditional compiled languages like C and Fortran.
