Goat Latin

LeetCode題目: 824. Goat Latin

My solution:

/**
 * @param {string} sentence
 * @return {string}
 */
let toGoatLatin = sentence => {
    const vowel = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'];
    return sentence.split(' ').map((word, idx) => {
        word = `${vowel.includes(word[0]) ? word : word.slice(1) + word.at(0)}ma`;
        for(let i=0; i<=idx; i++) word += 'a';
        return word;
    }).join(' ');
};
