each

Makes a new list of what an arrow gives for each entry of a list. The arrow holds what a body may hold, and a return inside it ends the arrow.

Example

const lines = each(rows, (o, i) => ({ place: i + 1, id: o.id }))

Returns

The new list, in order. Where waiting is allowed and the arrow answers a promise, the entries are taken one after another, and it answers a promise of the list.

Errors

code.T0013: an arrow that answers a promise where waiting is not allowed.

code.T0027: a value of another kind than the word works with, or a value past the limit valueSize.

code.T1014: a reference in the place of its list: it takes an arrow, which only a body and a view can hold.
