So you have fastn, and you are eager to start writing some ftd code. But before that let’s setup a decent programming editor. Programs are written in “plain text” files. Editing plain text files is usually done best with special text editors. We have many to chose from, old timers use ViM or Emacs. Then there are VSCode and Jetbrains family of editors. These editors not only are quite good at editing text files, they also come with a plathora of features, like file browser that lets you easily see all the files in your “project”, tools like Find and Replace to quickly find things across your files, and do mass replace, which can be handy if you change your mind about name of something for example.

Some of these editors also come with programming language specific tools, which let you perform operations related to specific tasks in that language etc. Some of these are also called “Programming IDEs”, integrated development environments.
