Can't work out the Typescript syntax for an empty array

[andrewpatto]

I can make a string array type with

e.array(e.str)

But I can't work out the syntax to make an empty instance of a string array?

e.array()

e.array([])

both fail with compile errors (so I can't even get an object to attempt to cast to my type - as I would do for empty sets)

You need to use e.literal like this:

e.literal(e.array(e.str), []);

Thanks! That "custom literals" info is on the Types page - not the Literals page of the documentation (where I was looking). Possibly some cross reference or something? The discussion for how to make Empty sets is on the Literals page, so I stopped looking there when I couldn't find anything about arrays.

Thanks for an awesome db - am really enjoying using edgedb.

In practice on execution I was then getting an 'indeterminate type' message - so I had to add a cast as well (as per the empty set example)

e.cast(e.array(e.str), e.literal(e.array(e.str), []));
