Capitalize the first letter of each word in Javascript

In this guide, we will look at writing a function that capitalizes the first letter of every word in JavaScript.

const capitalize = value => {
  if (!value) return "";
  return value
    .split(" ")
    .map(val => val.charAt(0).toUpperCase() + val.slice(1))
    .join(" ");
};

So basically we split the given string, using the space as a base. We went ahead to extract the first character using the charAt this we then change to an uppercase letter.
