    let numbers = '';
    let sum = 0;

    for (let i = startNum; i <= finalNum; i++) {
        if (i % 9 === 0) {
            sum += i;
            numbers += i + '\n';

РЕШЕНИЕ С МАСИВ И ЛАМБДА:

function numbersDivisibleOf9(input) {
    let startNum = Number(input[0]);
    let finalNum = Number(input[1]);
    let numbers = [];

    for (let i = startNum; i <= finalNum; i++) {
        if (i % 9 === 0) {
            numbers.push(i);
            i += 8;
        }
    }
    console.log(`The sum: ${numbers.reduce((a, b) => a + b, 0)}\n${numbers.join('\n')}`);
}

ИЛИ:

function numbersDivisibleOf9(input) {
    let startNum = Number(input[0]);
    let finalNum = Number(input[1]);

    let numbers = Array(finalNum - startNum + 1).fill().map((_, i) => startNum + i).filter(n => n % 9 === 0);
    console.log(`The sum: ${numbers.reduce((a, b) => a + b, 0)}\n${numbers.join('\n')}`);
