In this article, I will take you through the steps to install racket programming language on Ubuntu 20.04 LTS but before that let me ask you a quick question. Do you know which is the first language to support higher-order software contracts and safe gradual typing ? If your answer is Racket Programming Language then you are absolutely correct. It allows programmers to deploy these tools to harden their software. Not only this, Racket also allows developers to define their own loops with powerful macros. These macros are so powerful that programmers make entire domain-specific languages as libraries. No tools, no Makefiles required.

It includes a rich set of libraries, covering the full range from web server apps to mathematics and scientific simulation software. It has plenty of other features as well which makes it a easy choice for Developers and Programmers. We will the steps to install racket programming language on Ubuntu 20.04 LTS in great detail in below section. More on Racket Documentation.
