Convert camelCaseText to Sentence Case Text

Question

How can I convert a string either like \'helloThere\' or \'HelloThere\' to \'Hello There\' in JavaScript?

Answer 1

Adding yet another ES6 solution that I liked better after not being happy with a few thoughts above.

const camelize = (str) => str
    .split(' ')
    .map(([first, ...theRest]) => (
        `${first.toUpperCase()}${theRest.join('').toLowerCase()}`)
    )
    .join(' ');
