So generally going well.
Did chapters 21 and 22 today. Chapter 22 was good because it combined several things.
Chapter 20 was hard and I need to go back to it. It covered nested loops.
Svelte and Sapper
Had a quick look at these. Svelte is for single page apps. Sapper, I think, is for multi page apps. Seem like good things with properly reactive js in very small file sizes.
Probably need to learn a lot more JS first but Svelte certainly seems pretty good. Good online info including a free 7 hr vid on Youtube by freecodecamp.org:
