I got challenge number 3 wrong, as I used the each() method on the 'a' elements. Why not use it since we are iterating through all the list items' anchor tags?

Full Stack JavaScript Techdegree Graduate 18,394 PointsSorry! https://teamtreehouse.com/library/practice-working-with-jquery-collections, specifically the 3rd challenge in the app.js instructions.
This is the correct answer: $('a').attr('target', '_blank'); I deleted mine as I was going through the solution, but I don't understand why this is the case. Thanks in advance!

The main reason you might use "each" is when you want to so something with the collection that cannot be done by one of the built-in methods.
