Edit: i appreciate Go because there's not as much boilerplate or setup required as with some languages (unpack the tarball, set $PATH, and I'm off to the races) but even those steps mean we're talking about shells and directory trees.
Otherwise, it's really easy to get lost in boilerplate before you even know what the payoff is.
It's good to show what's possible but it isn't fun and will bore them to death fast because it's very limiting for beginners.
I can think of many ways to spark people's interest in cooking or music, but programming seems a bit harder to me. I never thought about why I love it, let alone why others should.
How would you do that?
Combining programming with music is a cool idea - https://sonic-pi.net/
Go is simple but not really beginner friendly. In my opinion teaching novices should start with Ruby (not Python or Javascript that's so often is the case). Show them how to do simple scripts, later build some games together.
Web-dev stuff like React, Webpack, Node etc should be out of the question, it would be a huge turn off for kids; heck it is that even for adults.
If you're going to start with web dev, better to teach teach plain HTML and CSS, and enough JS to make something small happen, then let them run with it and help them customize it. Something like an in-browser alarm clock would be interesting. Show them how to change the font, colors, sound, background image (maybe even a background slideshow), and some animations.
