Find the highest integer in the array using recursion

Create a function that finds the highest integer in the array using recursion.

Examples:

findHighest([-1, 3, 5, 6, 99, 12, 2]) ➞ 99

findHighest([0, 12, 4, 87]) ➞ 87

findHighest([6,7,8]) ➞ 8

const findHighest = (arr) => {
    if(arr.length === 1) {
        return arr[0];
    }
    let max = findHighest(arr.slice(1));
    return arr[0] > max ? arr[0] : max;
}

console.log(findHighest([-1, 3, 5, 6, 99, 12, 2])); // 99
