Why not use the JQuery each() method on challenge no. 3?

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?

Sorry! 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!

One of the advantages of jQuery is that when a jQuery object identifies a collection of elements, methods applied to that object affect all of the elements in the collection. So the "each" method is not needed.

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.
