expose isProps

[DanielMazurkiewicz]

There is this fragment in tagsNS:

let [props, ...children] = protoOf(args[0] ?? 0) === objProto ? args : [{}, ...args]

and for the sake of possibility of creating semi "custom tags" I would want to get exposed isProps to be able to detect if props are provided as first argument to my function:

let isProps = (o) => protoOf(o ?? 0) === objProto

and then line in tagsNS would look like that:

let [props, ...children] = isProps(args[0]) ? args : [{}, ...args]

If no one using isProps minifier should inline it back, so no size impact.

Thanks for the suggestion!

My current feeling is that since isProps function is quite easy to add on the client side (a just a couple lines of change) it probably doesn't have too much value to add another top-level function to VanJS.

btw: All top-level functions of VanJS are nested into a single van object when being exported. Thus that's not something minifier can trim off (this might be a design mistake of VanJS, but it's too late to fix).

Paste this code:

const test0 = () => console.log("test0");

const namespace = {
    test1: () => test0(),
    test2: () => console.log("test2")
}

namespace.test1();

To me looks like nothing that need to be fixed or changed with VanJS, whatever not used gets wiped out, whatever used once, gets inlined.
