firstChild property

Node? get firstChild

The read-only firstChild property of the Node interface returns the node's first child in the tree, or null if the node has no children.

If the node is a Document, this property returns the first node in the list of its direct children.

Note: This property returns any type of node that is the first child of this one. It may be a Text or a Comment node. If you want to get the first Element that is a child of another element, consider using Element.firstElementChild.

Implementation

external Node? get firstChild;
