What is the result type of the expression A!forEach(items: {1,2,3}, expression: fv!item + 1)?

The expression A!forEach(items: {1,2,3}, expression: fv!item + 1) evaluates each item in the provided list {1, 2, 3} and applies the specified expression, which is `fv!item + 1`, to each of these items. In this context, `fv!item` will represent each element of the array during the iteration. Therefore, the evaluation proceeds as follows: - For the first item (1): `1 + 1` results in `2` - For the second item (2): `2 + 1` results in `3` - For the third item (3): `3 + 1` results in `4` Thus, the results of applying the expression to the items are collected into a new list: {2, 3, 4}. This matches the reported answer, confirming that it is indeed the correct result type for the expression. Each choice encapsulates a different manipulation of the initial list or performs an operation inconsistent with the function applied in the given expression.

The expression A!forEach(items: {1,2,3}, expression: fv!item + 1) evaluates each item in the provided list {1, 2, 3} and applies the specified expression, which is fv!item + 1, to each of these items.

In this context, fv!item will represent each element of the array during the iteration. Therefore, the evaluation proceeds as follows:

  • For the first item (1): 1 + 1 results in 2

  • For the second item (2): 2 + 1 results in 3

  • For the third item (3): 3 + 1 results in 4

Thus, the results of applying the expression to the items are collected into a new list: {2, 3, 4}. This matches the reported answer, confirming that it is indeed the correct result type for the expression.
