Multiple Values for a Key

function solve(input) {
    let myMap = new Map();

    for (let i = 0; i < input.length - 1; i++) {
        let tokens = input[i].split(' ');

        let key = tokens[0];
        let value = tokens[1];

        if (myMap.has(key) === false) {

        }

        myMap.get(key).push(value);
    }

    let query = input[input.length - 1];

    if (myMap.get(query)) {
        console.log(myMap.get(query).join('\n'));
    } else {
        console.log('None');
