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

Without using regex just for reference:

String.prototype.toProperCase = function() {
  var words = this.split(' ');
  var results = [];
  for (var i = 0; i < words.length; i++) {
    var letter = words[i].charAt(0).toUpperCase();
    results.push(letter + words[i].slice(1));
  }
  return results.join(' ');
};

console.log(
  'john smith'.toProperCase()
)
