Modern JavaScript from the Beginning - Second Edition - InnerHTML Versus createElement()

The video tutorial explains how to create and add elements to the DOM using JavaScript. It covers two methods: a quick method using innerHTML and a cleaner, more efficient method using createElement and appendChild. The tutorial demonstrates creating a function to add list items with a title and button, highlighting the performance benefits of the cleaner method. It concludes with a preview of future topics, including creating reusable functions for buttons and icons.

What are the two main methods introduced for adding elements to the DOM?

• createDOM and appendDOM

• createElement and appendChild

• createNode and appendElement

• createHTML and appendHTML

What is a limitation of using the 'quick and dirty' method with innerHTML?

Why is the cleaner method more efficient than using innerHTML?

• Event handlers are deleted

• Event handlers are automatically created

• Event handlers are duplicated

• Event handlers are not automatically reattached

What will the next video focus on according to the transcript?

• Creating reusable functions for buttons and icons

• Deleting elements from the DOM
