Capitalizes the first letter of a string.
Use array destructuring and String.prototype.toUpperCase()
to capitalize first letter, ...rest
to get array of characters after first letter and then Array.prototype.join('')
to make it a string again.
Omit the lowerRest
parameter to keep the rest of the string intact, or set it to true
to convert to lowercase.
