-		//   respective virtual element
-		//- in order to support attaching `nodes` as a property of `cached`,
-		//   `cached` is *always* a non-primitive object, i.e. if the data was
-		//   a string, then cached is a String instance. If data was `null` or
-		//   `undefined`, cached is `new String("")`
-		//- `cached also has a `configContext` property, which is the state
-		//   storage object exposed by config(element, isInitialized, context)

-		//   it's an Array, it represents a list of elements; when it's a
-		//   String, Number or Boolean, it represents a text node

-		//They're artifacts from before arrays started being flattened and are
-		//likely refactorable
-		//`data` and `cached` are, respectively, the new and old nodes being

-		//reattach itself to the new parent)
-		//`editable` is a flag that indicates whether an ancestor is
-		//contenteditable
-		//`namespace` indicates the closest HTML namespace as it cascades down

-		//`configs` is a list of config functions to run after the topmost
-		//`build` call finishes running
-

-		//data are equivalent to empty strings
-		//- this prevents lifecycle surprises from procedural helpers that mix

+		 * `build` is a recursive function that manages creation/diffing/removal

+		 *
+		 * 1 - compare `data` and `cached`
+		 * 2 - if they are different, copy `data` to `cached` and update the DOM
+		 *     based on what the difference is
+		 * 3 - recursively apply this algorithm for every array and for the
+		 *     children of every virtual element
+		 *
+		 * The `cached` data structure is essentially the same as the previous
+		 * redraw's `data` data structure, with a few additions:
+		 * - `cached` always has a property called `nodes`, which is a list of
+		 *    DOM elements that correspond to the data represented by the
+		 *    respective virtual element
+		 * - in order to support attaching `nodes` as a property of `cached`,
+		 *    `cached` is *always* a non-primitive object, i.e. if the data was
+		 *    a string, then cached is a String instance. If data was `null` or
+		 *    `undefined`, cached is `new String("")`
+		 * - `cached also has a `configContext` property, which is the state
+		 *    storage object exposed by config(element, isInitialized, context)
+		 * - when `cached` is an Object, it represents a virtual element; when
+		 *    it's an Array, it represents a list of elements; when it's a
+		 *    String, Number or Boolean, it represents a text node
+		 *
+		 * `parentElement` is a DOM element used for W3C DOM API calls
+		 * `parentTag` is only used for handling a corner case for textarea
+		 * values
+		 * `parentCache` is used to remove nodes in some multi-node cases
+		 * `parentIndex` and `index` are used to figure out the offset of nodes.
+		 * They're artifacts from before arrays started being flattened and are
+		 * likely refactorable
+		 * `data` and `cached` are, respectively, the new and old nodes being
+		 * diffed
+		 * `shouldReattach` is a flag indicating whether a parent node was
+		 * recreated (if so, and if this node is reused, then this node must
+		 * reattach itself to the new parent)
+		 * `editable` is a flag that indicates whether an ancestor is
+		 * contenteditable
+		 * `namespace` indicates the closest HTML namespace as it cascades down
+		 * from an ancestor
+		 * `configs` is a list of config functions to run after the topmost
+		 * `build` call finishes running
+		 *
+		 * there's logic that relies on the assumption that null and undefined
+		 * data are equivalent to empty strings
+		 * - this prevents lifecycle surprises from procedural helpers that mix
+		 *   implicit and explicit return statements (e.g.
+		 *   function foo() {if (cond) return m("div")}
+		 * - it simplifies diffing code
