JS代码：js就很便捷！startsWith()

/**
 * @param {string} sentence
 * @param {string} searchWord
 * @return {number}
 */
var isPrefixOfWord = function(sentence, searchWord) {
    let arr = sentence.split(' ');
    for (let i = 0; i < arr.length; ++i) {
        if (arr[i].startsWith(searchWord)) {
            return i + 1;
        }
    }
    return -1;
};
