05. Sum Even Numbers

function solve(input) {
    let sum = 0;
    for (let i = 0; i < input.length; i ++){
        Number(input[i]) % 2 === 0 ? sum += Number(input[i]) : sum;
    }
    console.log(sum);
}

Решение със map(), filter() и reduce():

function solve(input) {

    let evenNum = input.map(Number).filter(a => a % 2 === 0);
    let sum = evenNum.reduce((a, b) => a + b, 0);
    console.log(sum);

}

Или:

function solve(input) {

    console.log(input.map(Number).filter(a => a % 2 === 0).reduce((a, b) => a + b, 0));

}
