'''Julia''' is a [[dynamic programming language|dynamic]] [[general-purpose programming language|general-purpose]] [[programming language]]. As a [[high-level programming language|high-level]] language, distinctive aspects of Julia's design include a type system with [[parametric polymorphism]], the use of [[multiple dispatch]] as a core [[programming paradigm]], [[just-in-time compilation|just-in-time]] (JIT) compilation and a parallel [[tracing garbage collection|garbage collection]] implementation. Notably Julia does not support [[Class (computer programming)|classes]] with [[Encapsulation (computer programming)|encapsulated]] methods but instead relies on the types of all of a function's arguments to determine which method will be called.
By default, Julia is run similarly to scripting languages, using its runtime, and allows for [[read–eval–print loop|interactions]],<ref name="PackageCompiler.jl" /> but Julia programs/[[source code]] can also optionally be sent to users in one ready-to-install/run file, which can be made quickly, not needing anything preinstalled.<ref name=AppBundler.jl /> <!-- controversial on Talk, page, for now commenting out, may move out of lead: Julia programs can also be (separately) compiled to [[binary executable]]s, even allowing no-source-code distribution, and the executables can get much smaller with Julia 1.12. Such compilation is not needed for speed, though it can decrease constant-factor startup cost, since Julia is also compiled when running interactively, but it can help with hiding source code. Features of the language can be separately compiled, so Julia can be used, for example, with its runtime or without it (which allows for smaller executables and libraries but is limited in capabilities). -->▼
Julia programs can reuse libraries from other languages
Julia is supported by programmer tools like IDEs (see below) and by notebooks like Pluto.jl, [[Project Jupyter|Jupyter]], and since 2025 [[Google Colab]] officially supports Julia natively.

Some state-of-the-art software has already been written in Julia, because it's considered easier to do then in the other popular languages. Some of it can also be used from other languages like Python or R. Julia was designed to be unusually easy to work with other languages, i.e. to benefit from code already written in other languages, to "reuse" their code.

Julia is sometimes used in [[embedded system]]s (e.g. has been used in a satellite in space on a [[Raspberry Pi]] Compute Module 4; 64-bit Pis work best with Julia, and Julia is supported in [[Raspbian]]).<ref>{{cite web |url=https://julialang.org/blog/2017/05/raspberry-pi-julia |title=Julia available in Raspbian on the Raspberry Pi |quote=Julia works on all the Pi variants, we recommend using the Pi 3.}}</ref>

In Julia, all concrete types are [[subtyping|subtypes]] of abstract types, directly or indirectly subtypes of the <code>Any</code> type, which is the top of the type hierarchy.
