FormData Constructor — append and get

📖 Usage Example

const fd = new FormData()
fd.set('a', '1')
fd.set('a', '2')
fd.get('a')  // → '2'

set() replaces any existing values for a key; append() does not.

FormData append and get

After appending a key/value pair you can retrieve it with get().

Challenge: Append key 'k' with value 'v' to a new FormData, then retrieve it with get.
