Javascript - lastChild

In JavaScript, the lastChild property returns the last child node of the specified element. This means that it returns the last child node of the DOM object, which can be an element node, a text node, or a comment node.

Syntax

nodeObject.lastChild

The nodeObject is the node object whose last child node you want to retrieve.

Return Value

The lastChild property returns the last child node of the specified node object. If there is no such node, it returns null.

Example

// Get the last child of the `<ul>` element
var list = document.getElementById("myList");
var lastItem = list.lastChild;

In this example, we use the getElementById method to get the reference to the ul element with the id attribute "myList". Then, we use the lastChild property to get the reference to the last child node of the ul element, which can be an element node, a text node, or a comment node.

Notes

• If you want to get the last "element" node, you can use the lastElementChild property instead.
• If you want to check if a node has any child nodes, you can use the hasChildNodes property.
• If you want to remove a node from its parent node, you can use the removeChild method.

Conclusion

In conclusion, the lastChild property is a useful tool when it comes to manipulating the DOM tree in JavaScript. It allows you to easily retrieve the last child node of a DOM object and manipulate it according to your needs.
