The 'insertBefore' method in the Javascript DOM allows you to insert a new node onto an existing parent node before one of the other child nodes. This is commonly used with HTML Elements (which are a type of Node).

In this video we see an example of insertBefore in action, by adding a new element to an unordered list somewhere in between. We also look at creating a function that does the opposite of 'appendChild', by inserting a Node at the beginning of another parent node.
