One can easily configure VSCode for Ruby with some steps mentioned below, but first, let’s see what these terms are. Ruby is nothing but a high-level and general-purpose programming language. It was developed by Yukihiro Matsumoto in the mid-1990s. It is a simple language because its syntax is more like the English language. In this language, everything is an object, including the primitive data types. It is used for web servers, DevOps, and web scraping. It’s also an open-source language with a big community, It’s a robust, dynamically typed, object-oriented language, and it has clean and simple syntax that allows users to solve problems with just fewer lines of code and write more appropriate code. 

Whereas Visual Studio Code, also commonly referred to as VSCode, can be classed as a development environment (IDE), meaning that developers can write and test code at the same time in the same place. VSCode supports multiple languages like C, C++, Python, Ruby, etc. it includes features like debugging, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git.

Steps to configure VSCode for Ruby 

Step 1: Install Ruby

All the latest versions of Ruby for Windows can be downloaded from Download the latest version. Also, you can follow this GFG article for more details on How to install ruby. When you install Ruby, also set its bin path in the Environment variable. To set its path, follow these steps (ignore this if you have already done it).

Step 4: Now your IDE is set to run Ruby. You can check by running an example ‘Hello world’ program. For that, create a new file ‘Test.rb’ the written code for printing hello world by writing this
