Function createTypedArray

Creates an array with length elements, in such a way that the output's type includes the length of the array. This function is equivalent to:

Array.from({length}, (_, i) => init(i)) as T[] & { length: L }
Copy

but less verbose.

This can be used to create arrays matching constructor types, for example:

const t = await nexus.createTransaction()
const rasselbock = t.create("rasselbock", {
  // requires an array of 32 elements
  patterns: createArray(32, () => ({
    // requires an array of 7 elements
    effectOrder: createArray(7, (i) => i),
   })),
})
