When I’m building a new script, I usually add the following function to the script and run the function before anything else. The script will exit immediately if any issues are found so I have a chance to correct things. If no issues are found, the script will simply continue.
It’s small and simple so it’s easy to remove when I’m done building a script.
script_check() {
if ! shellcheck "${0}"; thenexit 1
fi
}
script_check
Shellcheck has helped me learn a lot about scripting and I strongly recommend using it too.

That’s good. There are also editors that can run it for you and highlight the issues whilst you type, neovim being one.
Why wrap it in a function at all? Why not just put the if at the top of the file?
