+* Returns: {Array} of two [`Duplex`][] instances.
+
+The utility function `duplexPair` returns an Array with two items,
+each being a `Duplex` stream connected to the other side:
+
+```js
+const [ sideA, sideB ] = duplexPair();
+```
+
+Whatever is written to one stream is made readable on the other. It provides
+behavior analogous to a network connection, where the data written by the client
+becomes readable by the server, and vice-versa.
+
+The Duplex streams are symmetrical; one or the other may be used without any
+difference in behavior.
