How to Install Julia Programming Language on Linux ?

Julia is a programming language used for mathematical computations and scientific data analysis. Julia is an open-source high-performance language that is used to perform statistical calculations and general-purpose programming.

Getting Started with Julia

Julia programs can be written in any of the widely used text editors like Notepad, Notepad++, gedit, etc. or on any of the text-editors. One can also use an online IDE for writing Julia codes or can even install one on their system to make it more feasible to write these codes because IDEs provide a lot of features like intuitive code editor, debugger, compiler, etc.
To begin with, writing Julia Codes and performing various intriguing and useful operations, one must have Julia installed on their System. This can be done by following the step by step instructions provided below:
