My areas of focus are pretty different from that author&#x27;s - e.g. I haven&#x27;t tried contributing to the core language. But I&#x27;ve been using Julia for my research code for ~4 months now, and it&#x27;s been an absolute joy.<p>The language allows super-readable code while remaining quite fast. The sort of research I&#x27;m doing involves interacting a bit with data then doing a bunch of simulations, and Julia excels at this. The expressiveness in how Julia handles anonymous functions, optional arguments, tuple construction&#x2F;deconstruction, etc. allows for really concise configurations of how my little simulations run.<p>My only pain points:<p>- DataFrames are not as fast as the rest of the language.<p>- I&#x27;d like an infix function composition operator. (Possibly this exists, but I can&#x27;t find it in the documentation).<p>9.5&#x2F;10, absolutely recommend.
