> I'm usually concerned with how easy it is to manipulate text: sort, search, delimit, and replace substrings. Especially given an array or matrix of string data. No significant experience there. I would read http://docs.julialang.org/en/release-0.5/manual/strings/ http://docs.julialang.org/en/release-0.5/manual/strings/ and make sure that the data structures are adequate for your work. You can write C-like code and get C-like performance. Julia also makes it easy and efficient to pass data to and from C. Python/R/Matlab interop works nicely, but there's a cost. > Maybe the biggest concern is documentation for functions. Is it quick to look up any function? Is it quick to discover available functions relevant to a task? The docs are pretty terse: http://docs.julialang.org/en/release-0.5/stdlib/strings/ http://docs.julialang.org/en/release-0.5/stdlib/strings/ Google is pretty good for discovery, although not as good as for widely-used languages. Many people ask on the julia-users Google group, and almost every well-written question gets answered. Typing ?function_name in the REPL returns the function docstring, similar to Python, and does a (very-limited) look-up. I use Jupyter, and find the experience much better than in a REPL. I've tried Juno, and it's still too much of a WIP for me. YMMV.
