I have an Input which includes a string array (`subnetIds`) and need to convert it to an `Input&lt;string&gt;[]` (so an array of string inputs). How can I do this?

Figured it out:
```export const publicSubnetIds = infra.requireOutputValue('publicSubnetIds');
export const publicSubnetId1 = pulumi.output(publicSubnetIds)[0];
export const publicSubnetId2 = pulumi.output(publicSubnetIds)[1];```

There's  a few improvements that you can make there. _requireOutputValue_ returns a _Promise_ extracted from an _Output_, which you then immediately wrap in an _Output_ (twice). So you can replace _requireOutputValue_ with _requireOutput_ and then drop the two calls to _pulumi.output()_.

I'm not sure how `pulumi.output(publicSubnetIds)[0]` is working, since `pulumi.output(publicSubnetIds)` should be a _Promise&lt;string[]&gt;_ which isn't indexable. If there's some Pulumi magic and lifting going on, then great. Otherwise, that might be compiling because of the magic of _any_? Is it working in this form?

I would probably be looking to _await_ something in order to export subnet IDs from an awsx VPC...

I am not sure how it works either, but it does :smile:
