FormData iterators in JavaScript

FormData is an iterable. Accordingly, the values, keys, entries iterators are built into it.

Let's iterate over the values of form elements:

javascriptfor (let value of formData.values()) {
  console.log(value);
}

Now let's loop through the names of form elements:

javascriptfor (let key of formData.keys()) {
  console.log(key);
}

Now let's iterate over the key-value pairs of form elements:

javascriptfor (let entry of formData.entries()) {
  console.log(entry);
}
