Diffs two DOM elements' children, returning true if any changes were made.
This function performs an efficient diff between two DOM element trees and
applies the minimal set of changes needed to make the actual tree match the
expected tree. It handles adding, removing, and updating nodes as needed.
The diffing algorithm:
Compares children in order
Removes nodes that are no longer needed
Adds new nodes where necessary
Updates existing nodes in place when possible
Recursively diffs child elements
Parameters
$expectedRoot: HTMLElement
The DOM element representing the desired state
$actualRoot: HTMLElement
The DOM element to be updated to match the expected state
Returns boolean
true if any changes were made to the actual DOM, false otherwise
