Convert string to title case with JavaScript

Question

Is there a simple way to convert a string to title case? E.g. john smith becomes John Smith. I\'m not looking for something complicated like John R

Answer 1

Use /\S+/g to support diacritics:

function toTitleCase(str) {
  return str.replace(/\S+/g, str => str.charAt(0).toUpperCase() + str.substr(1).toLowerCase());
}

console.log(toTitleCase("a city named örebro")); // A City Named Örebro

However: "sunshine (yellow)" ⇒ "Sunshine (yellow)"
