Julia is a high-level dynamic programming language designed to address the needs of high-performance numerical analysis and computational science, without the typical need of separate compilation to be fast, while also being effective for general-purpose programming, web use or as a specification language. Distinctive aspects of Julia's design include a type system with parametric polymorphism and types in a fully dynamic programming language and multiple dispatch as its core programming paradigm. It allows concurrent, parallel and distributed computing, and direct calling of C and Fortran libraries without glue code. Read more on Wikipedia...

Example from Riju:
println("Hello, world!")
Example from hello-world:
println("Hello World")
# Hello world in Julia println("Hello, World!")
Example from Linguist:
#!/usr/bin/env julia # From help_screen = """ usage: fullpath *[relative-paths] [-c] Prints the fullpath of the paths If no paths are given as args, it will read them from stdin If there is only one path, the trailing newline is omitted The -c flag will copy the results into your pasteboard """ help = false copy = false dir = pwd() paths = [] for arg = ARGS if arg == "-h" || arg == "--help" help = true elseif arg == "-c" || arg == "--copy" copy = true elseif arg != "" push!(paths, arg) end end if help print(help_screen) exit() end function notempty(string) return !isempty(string) end if length(paths) == 0 paths = filter(notempty, map(chomp, readlines())) end function print_paths(stream, paths) if length(paths) == 1 path = paths[1] print(stream, "$dir/$path") else for path = paths println(stream, "$dir/$path") end end end if copy read, write, process = readandwrite(`pbcopy`) print_paths(write, paths) close(write) end print_paths(STDOUT, paths)
Example from Wikipedia:
julia> p(x) = 2x^2 + 1; f(x, y) = 1 + 2p(x)y julia> println("Hello world!", " I'm on cloud ", f(0, 4), " as Julia supports recognizable syntax!") Hello world! I'm on cloud 9 as Julia supports recognizable syntax!
