Confused between For and index
Could someone please explain this a little more in depth, I am not able to follow the explanation on the tutorial.

In simplest terms, with
For the value is reactive. With Index the index is reactive.
So if you want to redraw when a value changes, use for. If you want to redraw when an item in the array is added/removed, use indexWhat if both need to be reactive? :solid:
Maybe nesting those components?
There is https://primitives.solidjs.community/package/list where both index and the element are a signal
Solid Primitives
A library of high-quality primitives that extend SolidJS reactivity
But there are little use cases for it. It came in handy one time where I received immutable data from another library and I didn't know about reconciled
merge option.
