Julia is a high-level general-purpose
[12]
dynamic programming language that was originally designed
to address the needs of high-performance numerical analysis and computational science , without
the typical need of separate compilation to be fast,
[13] [14] [15] [16]
also usable for client and server web use,
[17] [18]
low-level systems programming
[19]
or as a specification language .
[20]
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 .
Julia is garbage-collected ,
[21]
uses eager evaluation and includes efficient libraries for floating-
point calculations, linear algebra , random number generation , and regular expression matching.

Many libraries are available, and some of them (e.g. for fast Fourier transforms ) were previously
bundled with Julia.

History
[ edit ]
Work on Julia was started in 2009, by Jeff Bezanson, Stefan Karpinski , Viral B. Shah , and Alan
Edelman , who set out to create a free language that was both high-level and fast. On 14 February
2012 the team launched a website with a blog post explaining the language's mission.

Karpinski
said of the name "Julia": "There's no good reason, really. It just seemed like a pretty
name."
[24]
Bezanson said he chose the name on the recommendation of a friend.
