If you want to validate a URL in JavaScript, chances are you’re using a regular expression, using a library or a try/catch block:

try {
  new URL("https://webfromthefuture.com");
} catch (e) {
  console.log("invalid URL");
}

There’s a better way, using the URL.canParse() method. A static method that returns a boolean telling whether the URL is valid:

URL.canParse("https://webfromthefuture.com"); // true
URL.canParse("/not-a-valid-url"); // false
URL.canParse("/features/url-canparse", "https://localhost:3000"); // true
