Learn Lua in Neovim: Comments & User Input — io.read() & tonumber() | Episode 6

Make your Lua programs interactive! In this episode we cover single-line and multi-line comments, toggle comments with Comment.nvim (gcc and V+gc), then read input from the user with io.read() and convert it to a number with tonumber(). Interactive scripts run in a split terminal inside Neovim. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace.
