Renders an <input> element that uses a callback function to pass its value to the parent component.

• Use object destructuring to set defaults for certain attributes of the <input> element.
• Render an <input> element with the appropriate attributes and use the callback function in the onChange event to pass the value of the input to the parent.

function UncontrolledInput({ callback, type = 'text', disabled = false, readOnly = false, placeholder = '' }) {
  return (
    <input
      type={type}
      disabled={disabled}
      readOnly={readOnly}
      placeholder={placeholder}
      onChange={({ target: { value } }) => callback(value)}
    />
  );
}

ReactDOM.render(
  <UncontrolledInput type="text" placeholder="Insert some text here..." callback={val => console.log(val)} />,
  document.getElementById('root')
);
