Make the first letter of a string toUpperCase in JavaScript


How do I make the first letter of a string uppercase in JavaScript?
What is the best approach to capitalize words in a string?

  • Change all string to lowercase.
  • The regex matches the first letter of each word within the given string and transforms only that letter to uppercase.
  • \b matches a word boundary (the beginning or ending of word);
  • \w matches the following meta-character [a-zA-Z0-9].
