The FormData.entries() method returns an iterator which iterates through all key/value pairs contained in the FormData. The key of each pair is a string object, and the value is either a string or a Blob.

None.

An iterator of FormData's key/value pairs.

formData.append("key1", "value1");
formData.append("key2", "value2");

// Display the key/value pairs
for (const pair of formData.entries()) {
  console.log(`${pair[0]}, ${pair[1]}`);
}

The result is:

key1, value1
key2, value2
