Julia feels really good. Multiple ways of doing things, so I can choose what's appropriate for each context. Lots of useful little tools built into the language, neat syntax, and the REPL is really useful for messing around and figuring things out before writing them into a program.

IJulia/Jupyter is pretty good, and almost indispensable for most real-world Julia projects. But this JuliaCon got me excited for when Pluto (https://www.youtube.com/watch?v=IAF8DjrQSSk) becomes stable and polished. It fits my mental models better and seems to be taking ambitious steps beyond what Jupyter does, in the right directions.
that looks nice indeed! and it kinda plays julia's strengths over python, being statically analyzable in a way.
