pattern can be a string or a RegExp, and the
replacement can be a string or a function to be called for each match. We passed the Regular Expressions as a pattern where it looks for lowercase words matches. Next is we used a function as the replacement which then converts each word matches to uppercase.

You can pass a word:
capitalizeEachWord('ohayō'); // Result: "Ohayō"
You can pass a sentence:
capitalizeEachWord('hello, luigi!'); // Result: "Hello, Luigi!"
