What is the difference between Lists.find() and Lists.find().fetch()?

1

The difference is that Lists.find() is reactive
and
Lists.find().fetch() is not reactive ?

Probably a silly question for someone with meteor experience.

2

The first one returns a cursor while the second one returns an array. Nothing to do with reactivity.

Would you mind explaining the difference, and use cases? :slight_smile:

Check those links for cursor definition:

so both are reactive ?
when you return a cursor from a template helper,
it behaves like an array.

Yes both are reactive.

Yes, essentially it does act like an array, even though it’s not. Blaze is just smart enough to recognize a cursor and iterate over the elements (documents) it contains, if you’re using an {{#each lists}} ... {{/each}} construct.
