A text editor is by far the most used developer tool regardless of what type of developer you are. A good text editor can help you write better code with real-time code checking, syntax highlighting, and automatic formatting.
Rich text editors, such as Microsoft Word and Libre-Office Writer, are great for writing a paper, but the features that make them good at creating nicely formatted documents make them unsuitable for writing code. A document created with these rich text editors has more than just text embedded in the file. These files also contain information on how to display the text on the screen and data on how to display graphics embedded into the document. In contrast, plain text editors, such as VSCode and Sublime, don't save any additional information. Saving only the text allows other programs, like Ruby's interpreter, to read and execute the file as code.
You can think of code editors as specialized web development tools. They are highly customizable and offer many features that will make your life easier. There is nothing worse than spending 2 hours trying to figure out why your program isn't working only to realize that you missed a closing bracket. Plugins, syntax highlighting, auto-closing of brackets and braces, and linting are just a few of the benefits of using a code editor. There are many text editors out there to choose from, but we suggest starting with VSCode.
VSCode is an excellent free code editor. It has outstanding add-on support and great Git integration. VSCode is the most popular code editor, so support is easy to find in the community. You can download the .deb file and install it from here.
Which editor you use is generally a matter of preference, but for the purposes of this course, we are going to assume you're using VSCode, mainly because it's free, it's easy to use, and it works pretty much the same on every operating system. If you want to use something else, do it.
As a reminder, if you're using a virtual machine, you should install your text editor of choice on your VM. You're welcome to also install it on your host (i.e., your Windows main OS), but you'll want to be sure that you have this critical tool inside your VM.
