Creates a new tuple containing only the elements at the specified indices.

When to use

Use to select a subset of elements from a tuple by position.

Details

The result order matches the order of the provided indices.

Example (Selecting elements by index)

const result = Tuple.pick(["a", "b", "c", "d"], [0, 2, 3])
console.log(result) // ["a", "c", "d"]

• get – extract a single element
