 A `TypeError` will be thrown if `array` is not an `Array`.
 
+`Buffer.from(array)` may also use the internal `Buffer` pool like
+[`Buffer.allocUnsafe()`] does.
+
+```js
+const nodeBuffers = Buffer.from([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
+
+console.log(nodeBuffers.offset);
+// prints: 344
+
+// Default Buffer.poolsize is 8192
+console.log(Buffer.poolSize);
+// prints: 8192
+
+// But you can change it
+Buffer.poolSize = 5;
+
+const buf = Buffer.from([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
