# Hints
|
||
|
|
|
||
|
|
## 1. Create an empty list
|
||
|
|
|
||
|
|
Creating an empty list is just like creating a list with items. It can be done using `list` or using `quote` on an empty list.
|
||
|
|
|
||
|
|
## 2. Add a new language to the list
|
||
|
|
|
||
|
|
Clojure has a core function that can [prepend an item to a list](https://clojuredocs.org/clojure.core/cons).
|
||
|
|
|
||
|
|
## 3. Check the language last added
|
||
|
|
|
||
|
|
Like other Lisps, Clojure has a function that [returns the first item from a list](https://clojuredocs.org/clojure.core/first).
|
||
|
|
|
||
|
|
## 4. Remove the first language from the list
|
||
|
|
|
||
|
|
Likewise, Clojure also has a function for [returning a list with the first item removed](https://clojuredocs.org/clojure.core/rest).
|
||
|
|
|
||
|
|
## 5. Count the languages in the list
|
||
|
|
|
||
|
|
The [number of items](https://clojuredocs.org/clojure.core/count) in a list can easily be returned using a Clojure core function.
|
||
|
|
|
||
|
|
## 6. Put it all together
|
||
|
|
|
||
|
|
Remember that function calls can be nested.
