 If you've programmed in another language before, you might be wondering if `conj` changes the vector. It's important to note that it does not. All collections in Clojure are _immutable_--that is, unchangeable. When we say that a function "adds to" or "removes from" a collection, what we mean is that the function returns a new collection with an item added or removed.
 
-Now, take a look at the last three functions. `count` does what you'd expect: it gives us a count of the number of items in a vector. `nth` gives us the nth item in the vector. Note that we start counting at 0, so in the example, calling `nth` with the number 1 gives us what we'd call the second element when we aren't programming. `first` returns the first item in the collection. Try not to think about that and `nth` at the same time or your brain will fry.
