zip
Function
A fixed-size array built from two of one length, element by element: zip(xs, ys, (a, b) => a * b).
The signature and the sentence under each name are the compiler's own text at commit 26de7be8.
Syntax
declare function zip<A, B, R, N extends number>( xs: array<A, N>, ys: array<B, N>, f: (a: A, b: B) => R,): array<R, N>A number in a parameter or a return position is the scalar slot. The ambient file declares a GPU scalar as a branded number whose brand is optional, so a literal and any branded scalar both fill it.
type f32 = number & { readonly [f32Tag]?: true }
A declaration you write still needs a width, and a bare number on a field or a parameter is refused; the TypeScript constructs page carries that row with the compiler's own message.
Parameters
Return value
array<R, N>
Description
Unrolled into one call per element; the function may read the variables around it.
