moveToIdx
Moves the element at the startIdx to the specified endIdx without leaving any gaps. This behavior can be thought about as "drag 'n' drop" style, rather than something like swapAt.
import { arr } from "@tsly/arr";
const fruit = ["apple", "banana", "orange", "pear", "kiwi"];
console.log(arr(fruit).moveToIdx(1, 3).take());
// ["apple", "orange", "pear", "banana", "kiwi"]
