Convert JavaScript object into URI-encoded string

Question

I got a JavaScript object which I would like to get x-www-form-urlencoded.

Something like $(\'#myform\').serialize() but for objects.

Answer 1

I'm surprised that no one has mentioned URLSearchParams

var prms = new URLSearchParams({
  firstName: "Jonas",
  lastName: "Gauffin"
});
console.log(prms.toString());
// firstName=Jonas&lastName=Gauffin
