Arrays: Left Rotation.js

const a = [1, 2, 3, 4, 5]
const d = 4

function rotLeft(array, shift) {
	const newArr = []

	for (let index = 0; index < array.length; index++) {
		const newIndex = Math.abs(index - shift + array.length)
		newArr[newIndex] = array[index]
	}

	return newArr
}

const rotated = rotLeft(a, d)
console.log(rotated)
