Answer 1

Hello, Dennis Simiyu !
If you have in mind how to use the Ruby editor on SoloLearn. You need to go to the "my codes" tab. Then choose the desired language, you will have it "Ruby".

For Ruby you can simply download the compiler from https://www.ruby-lang.org/en/downloads. Then you can either use the interactive ruby console (Irb) for simple practice or write ruby code in any simple word processor e.g. notepad and save using the .rb extension. From there, you can use command prompt to open it.
If you know how to use command prompt on windows or in any other operating system, you first need to go to where you saved the ruby file and then type: ruby name_of_file.rb
Or you can open the application formed when you save the file.
