For intro to vimscript, it might be helpful to mention sourcing the file first. I had to give it a quick google. but I needed to source the file before my scripts would work. I think this isn’t needed if it’s in the vimrc, but I don’t think these are needed for that.

> "hey".to_i
=> 0
> "8 days a week".to_i
=> 8
pretty similar to vimscript!
