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.
const capitalizeEveryWord = str => str.replace(/\b[a-z]/g, char => char.toUpperCase());

decapitalize
Decapitalizes the first letter of a string.
Use array destructuring and String.toLowerCase() to decapitalize first letter, ...rest to get array of characters after first letter and then Array.join('') to make it a string again. Omit the upperRest parameter to keep the rest of the string intact, or set it to true to convert to uppercase.

escapeHTML
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).
