One-liner to convert a string to title case in JavaScript

You can use the toTitleCase() function to convert a string to title case in JavaScript:

const toTitleCase = (str) =>
  str.replace(
    /\w\S*/g,
    (txt) => txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase()
  );

Then, you can call this function on a string like this:

const myString = "this is a string";
const titleCaseString = toTitleCase(myString);
console.log(titleCaseString); // This Is A String
