If you enjoy using Ramda like I do, you can do this clean fun thing:

import { concat, compose, head, join, map, split, tail, toLower, toUpper } from 'ramda';    
const toWords = split(' ');
const capitalizeWords = map(s => concat(toUpper(head(s)), toLower(tail(s))));
const toSentence = join(' ');
const toTitleCase = compose(toSentence, capitalizeWords, toWords);

or of course you can always cut it down to

const capitalizeWords = map(s => concat(toUpper(head(s)), toLower(tail(s))));
const toTitleCase = compose(join(' '), capitalizeWords, split(' '));
