Odd Occurrences JS Fundamentals

function oddOccurrences(input) {
    let oddWords = {};
    let sentence = input.split(' ');

    for (let word of sentence) {
        let key = word.toLowerCase();
        if (oddWords.hasOwnProperty(key)) {
            oddWords[key]++;
        } else {
            oddWords[key] = 1;
        }
    }
    let sortedWords = Object.entries(oddWords).filter(entry => entry[1] % 2 !== 0)
    sortedWords.sort((a, b) => b[1] - (a[1]));

    let result = sortedWords.map(entry => entry[0]);
    console.log(result.join(' '));
