capitalizeEveryWord
Capitalizes the first letter of every word in a string.
Use String.replace() to match the first character of each word and String.toUpperCase() to capitalize it.

Escapes a string for use in HTML.
Use String.replace() with a regexp that matches the characters that need to be escaped, using a callback function to replace each character instance with its associated escaped character using a dictionary (object).
