How to create an object with type array_like<float>?

There are some apis accept parameters with type array_like<'a>, but i can not find any way to create a value with that type.
The api with array_like<'a> parameters are blow:

I thought array_like was just for binding to JS, and those from functions were for casting values passed from JS APIs that have array_like return values.

To create a Float32Array from an array<float> in ReScript you could use make instead of from

Currently, there is no way to create a TypedArray from literal except you create a binding to do this.

In ts/js, you can do this

const array = new Uint8Array([1, 2, 3, 4])

In @rescript/core, this is possible:

let array =  Uint8Array.make([1, 2, 3, 4])

Or (if you are not using @rescript/core) you could use Js.TypedArray2.Uint8Array like so:

let array = Js.TypedArray2.Uint8Array.make([1,2,3,4])
