Two questions, one about print() and one about else/else if

Question

How does print work? If we ever went over that, I missed it. What is the difference between print and document.write? Are they both methods?
What is the difference between:
```JavaScript
else {
  if () {
  }
}
```
As shown in the video, and:
```JavaScript
else if () {
}
```
Like we were taught?

The "print" function was introduced at about 3:45 in the Useful Array Methods (https://teamtreehouse.com/library/useful-array-methods) video.  It is not one of the array methods, it was just provided as a handy way to display some text on the web page.  As it is, there's no significant difference between it and "document.write", since all it does is call the other one internally.  But that could be changed later.
If no code is added except within the inner block, there is no functional difference between the two examples you have shown above.  The potential advantage of the first form is when you want to do something in the "else" case in addition to what is in the "if".  And the advantage of the second form is that you may add more "else if" cases after the block and/or a final "else" clause.
