How to Capitalize Every Word in JavaScript

To capitalize every word in a string using JavaScript, you can use the String.prototype.replace() method to match the first character of each word, and then use the String.prototype.toUpperCase() method to capitalize it.

Here's an example code snippet you can use:

const capitalizeEveryWord = (str) =>
  str.replace(/\b[a-z]/g, (char) => char.toUpperCase());

To use this function, pass in the string you want to capitalize as an argument, like this:

capitalizeEveryWord("hello world!"); // 'Hello World!'

This will return the capitalized string 'Hello World!'.
