- *
- * 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
