Further reading
Vimscript is a long and complex topic, and this chapter only brushes it. If you want to learn more, there are a few options.
You can read :help eval, which contains most of the information about Vimscript, as well as :help vim9, :help usr_51.txt, and :help usr_52.txt (which cover writing plugins) to learn more about Vim9script.
You can also choose to follow a tutorial online or pick up a book. A lot of people recommend Learn Vimscript the Hard Way by Steve Losh. It’s available online at http://learnvimscriptthehardway.stevelosh.com/ (you can buy a paper copy from the website as well).
