Move an element from an array position to another

Imagine that you have an array of fruits and you want to move an element from index = 1 to index = 3:

javascript
// Array of fruits, you'll move the apple before the watermelon
let fruits = ['Grape', 'Apple', 'Kiwi', 'Mango', 'Watermelon'];

let moveElem = ((from, to, arr) => {

    // Deletes the element from old position
    let [elem] = arr.splice(from, 1);

    // Inserts the element into new position
    arr.splice(to, 0, elem);

})(1, 3, fruits);

console.log(fruits); // ["Grape", "Kiwi", "Mango", "Apple", "Watermelon"]
