Does anyone know of any good tutorials, courses, videos, etc that would really help me work through Eleventy much faster? Anything outside of the basic documentation on their website.
You can always start by looking at their tutorials page - https://www.11ty.dev/docs/tutorials/ I’ve documented some of my own struggles with 11ty and Nunjucks vs Liquid in this thread here - How do you create new taxonomies with Eleventy?. I was also recommended this video and it was fairly useful as well https://www.youtube.com/watch?v=j8mJrhhdHWc
I think this should get you started. For anything more, I think you will have to wait for @hankchizljaw to finish his 11ty course.
