Julia is a dynamic, high-level programming language with high performance and speed that is used to perform operations in scientific computing. It is great for computational complex problems. It is an open-source language so all source code is available easily online.

It is as easy to use as Python but it has much faster execution compared to R and Python. Julia is a general-purpose language and can be used for various tasks such as statistical computations, data analysis, web development, game development and more.

Note: Julia programs are to be saved in a file with .jl extension.

Ways to run Julia

  • Through a .jl file in an IDE
  • Command by command in Julia REPL (Read Evaluate Print Loop)

It is easier to code and learn Julia as it is a lot similar to other mostly used languages syntactically.

Simple Julia Program

This is a simple program that prints GeeksforGeeks, just type the following code after the start of the interpreter.


# Julia code to print GeeksforGeeks
# print function

Characters in Julia

In Julia, a Char(character) value represents a single character. Characters in Julia are 32-bit primitive data types. It has a special literal representation and appropriate arithmetic behaviours and these can be converted into a numeric value that represents a Unicode code point.

Other subtypes of AbstractChar may be defined by Julia packages. Forex: optimization of operations for other text encodings.

Let’s see the usage of characters in Julia language.


This example shows how to work with Char in Julia.


ch = 'a'
# Converting a Char to its integer value
ch = Int('a')
# typeof(ch) will be Int32 on 32-bit architectures
# Converting integer back to a Char
