Full Stack JavaScript Techdegree Student 5,006 PointsAccording to StackOverflow, using [0] would find the first tag in the document and target that. This is useful if you have multiple tags with the same name ("p", for example). However, I would think it'd be better to target by ID in this case, vs by tag. In your example, I don't think there's a difference because you should only have one body tag.

The getElementsByTagName() method returns a collection of all elements in the document with the specified tag name, as a NodeList object.
The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0
Just because you have one Body tag it still comes up as an array.
