Julia version 1.0 was released on 08 Aug 2018. Julia was specifically designed for scientific and numerical computing. Although it is a flexible and dynamic language, it can achieve performance comparable to traditional statically-typed languages like C or Fortran. See The Julia Programming Language home page and read the Julia 1.0 release blog post for a general overview of the language.

Quick Start with Julia¶
Starting an interactive julia session. To exit the interactive session, type CTRL-D or type exit().
$ /shared/opt/julia-1.0.0/bin/julia julia >
To obtain help type a ? at the Julia> prompt:
julia> ? help?> Welcome to Julia 1.0.0. The full manual is available at https://docs.julialang.org/ as well as many great tutorials and learning resources: https://julialang.org/learning/ For help on a specific function or macro, type ? followed by its name, e.g. ?cos, or ?@time, and press enter. Type ; to enter shell mode, ] to enter package mode. julia>
Try getting help on the cosine function by typing

Invoking the Julia package manager can be done in either of two ways:
julia> using Pkg julia> Pkg.status() Status `~/.julia/environments/v1.0/Project.toml` [c5f51814] CUDAdrv v0.8.5 [91a5bcdd] Plots v0.19.2 julia>
or by using the interactive command-line invoked by typing the
julia> ] (v1.0) pkg> status Status `~/.julia/environments/v1.0/Project.toml` [c5f51814] CUDAdrv v0.8.5 [91a5bcdd] Plots v0.19.2 (v1.0) pkg>
You should definately read the package manager documentation as this covers some of the useful features of Julia for repoducible research using Project and Manifest files.
