): OmitTuple<T, I[number]>

Creates a new tuple with the elements at the specified indices removed.

When to use

Use to drop elements from a tuple by position.

Details

Elements not at the specified indices are kept in their original order.

Example (Removing elements by index)

import { Tuple } from "effect"

const result = Tuple.omit(["a", "b", "c", "d"], [1, 3])
console.log(result) // ["a", "c"]
