In this video i will talk about how to Insert Before an Element in JavaScript.

The insertBefore() method inserts a node as a child, right before an existing child, which you specify.

Tip: If you want to create a new list item, with text, remember to create the text as a Text node which you append to the li element, then insert li to the list.

You can also use the insertBefore method to insert/move an existing element.

The Node.insertBefore() method inserts a node before a reference node as a child of a specified parent node.

If the given node already exists in the document, insertBefore() moves it from its current position to the new position. (That is, it will automatically be removed from its existing parent before appending it to the specified new parent.)

This means that a node cannot be in two locations of the document simultaneously.
