 This looks very similar to how you access the items in an array, and it is basically the same thing — instead of using an index number to select an item, you are using the name associated with each member's value.
 It is no wonder that objects are sometimes called **associative arrays** — they map strings to values in the same way that arrays map numbers to values.

 However there are some cases where you have to use brackets.

 Unlike with a pull underlying byte source, data can arrive at any time.
 Therefore the underlying source must use `controller.byobRequest` to transfer incoming data if one exists, and otherwise enqueue the data into the stream's internal queues.

+Further, since the data can arrive at any time the monitoring behavior is set up in the `underlyingSource.start()` callback function.
 
 The example is highly influenced by a push byte source example in the stream specification.
 It uses a mocked "hypothetical socket" source that supplies data of arbitrary sizes.
-The reader is deliberately delayed at various points to allow the underlying source to use both transfer and enqueing to send data to the stream.

 Since data can arrive at the socket before the consumer is ready to handle it, everything about reading the underlying source is configured in the `start()` callback method (we don't wait on a pull to start handling data).
