Capitalize each word

A JavaScript exercise from Scriptdrill. Solve it with a code editor in your browser that runs your function against example and hidden tests, and it is checked the moment you submit.

The task

Words are separated by single spaces. Uppercase the first character of every word and lowercase the rest of it. Keep the spacing exactly as it is, including repeated spaces and spaces at the ends.

What this exercise teaches

Splitting on a single space keeps empty strings where spaces repeat, and joining with a single space restores the original spacing. Using the first character and slice(1) works for accented letters too, unlike a regular expression with \b, which only knows ASCII letters.

A hint if you get stuck

Split on `" "` (not on `/\s+/`), so empty strings between repeated spaces survive and the join puts the spaces back. Skip empty words.
