Julia is a high-performance language for scientific computing, which also happens to be readable. Julia may be the best choice for our work, though there may be times when your collaborators want to use Python or R, or when tools already exist in those languages that are perfect for a particular project.
Use the current stable release of Julia.
If you’re coming from MATLAB or Python, here is a useful cheatsheet for translating common operations into Julia.
A good introduction to Julia is Introduction to Computational Thinking, an online course from MIT.
