Julia is a dynamic general purpose programming language popular for scientific computing and big data analytics. It is extremely fast thanks to its use of a JIT compiler and allows developers to write concise, yet powerful code.

It's a general purpose language, but is most well known for its use in numerical analysis, data visualization, and machine learning.
It's fast because unlike most high level languages, it uses a just in time compiler to convert your source code into machine code before running it.
And unlike most dynamic languages, computers.
It has a flexible parametric type system.
That means static typing is optional by default and types can take parameters allowing one type to represent many different possibilities.
This opens the door to the multiple dispatch pattern where one function can have multiple methods or implementations based on its input parameters, and the language will determine which method to dispatch at runtime.
In fact, even operators like plus are functions that use multiple dispatch to handle a variety of different type combinations.
To get started, install Julia, then create a file ending in dot jl.
Declare a variable by providing a name, then assign a value to it.
Name support UTF8 like emojis or mathematical symbols.
It uses symbols to represent built in constants like pi, allowing you to write equations more elegantly in your code.
Like Perl, it's very good at string parsing and supports multiple expressions on a single line resulting in terse yet powerful code.
Define a function with the function keyword and close with the end keyword or shorten it to a single line with the equal sign or because functions are first class objects, they can be assigned to a variable or passed to another function anonymously.
What's interesting no.
Is that by default, a function is untyped, which means it implements one method to handle all inputs.
If the function is redefined, but this time with a type for the arguments, a another method is added to it.
When this function is called at runtime, Julia will look at the type of the arguments and dispatch the corresponding method.
In we can pass a type as a parameter, then use keywords like where to perform logic on the type itself.
In this case, it will assert that both types are the same.
Now, Julia is not an object oriented language in the classic sense.
However, it does support composite types with structs, which contain multiple fields and optional types.
Like any good scientific language, It has very well thought out support for arrays, with many built in functions to initialize and compute values over multidimensional arrays.
It supports asynchronous computing with its task model, which can pause and synchronize the execution of code like coroutines in other languages.
And finally, when it comes to big data, it can even distribute process into multiple memory spaces or machines and run natively on a GPU.

In this video, the host explains the capabilities of Julia, a dynamic programming language used for scientific computing. The language uses a flexible parametric system and supports multiple dispatch patterns, allowing for multiple methods to be used depending on input parameters. Julia also supports multiple data types and supports IO computing, including a task model and asynchronous computing. The language is not an object-oriented language and can even distribute data into multiple memory spaces or machines.

Julia, a dynamic general purpose programming language capable of high performance scientific computing with high level code. It was created in 2012 by a gang of scientists, who set out to build a language with the speed of c, the dynamism of Ruby, the practicality of Python that can do statistics like and linear algebra like MATLAB out of the box. It's a general purpose language, but is most well known for its use in numerical analysis, data visualization, and machine learning. It's fast because unlike most high level languages, it uses a just in time compiler to convert your source code into machine code before running it. And unlike most dynamic languages, computers.
