TS JS JS

Capitalizes the first letter of every word in a string.

Use String.prototype.replace() to match the first character of each word and String.prototype.toUpperCase() to capitalize it.

const capitalizeEveryWord = (str: string = "") =>
  str.replace(/\b[a-z]/g, (char) => char.toUpperCase());
capitalizeEveryWord("hello world!"); // 'Hello World!'
