template x-for, how to use the "key" keyword

[ericxin1982]

Hi Team,

I am learning alpine, and see template x-for, which has key this keyword, and I try to explore the value from loop, but it failed, it said key is not defined, how to figure this out?

Thanks

The key isn't available in the state.

It's only used internally by the x-for directive.

You don't access it, it is simply used to keep track of which elements are what during looping.
