Convert a string to title case

toTitleCase.js

/**

 * @param {string} str The string to convert.
 * @returns {string} The converted string.
 */
function toTitleCase(str) {
  return str
    .toLowerCase()
    .split(" ")
    .map(function (word) {
      return word.charAt(0).toUpperCase() + word.slice(1);
    })
    .join(" ");
}

Please note: this is my adaptation of a function written by Sonya Moisset. All I did was rewrite it in my preferred style using the array map() method instead of a for loop.
