+# TP javascript : riot.js
+
+La [documentation](https://riot.js.org/) de riot.js 
+
+#### Ex1
+Voici un [exemple](./src/ex1)  d'application (todo list) écrite avec riot.js.
+
+<div align="center">
+<img src="./img/todo.png">
+</div>
+
+
+
+Le but est de comprendre le code pour prendre en main Riot.js
+
+- Complétez la fonction `add` qui permet d'ajouter une tâche.
+- Faites en sorte que le bouton `clear done` soit desactivé quand il n'y a pas de tâches accomplies.
+- Complétez la fonction `clear` qui retire les tâches accomplies.
+- Mettez en oeuvre les filtres `All`, `Active` et `Done`.
+- Complétez le code qui permet de supprimer une tâche.
+- Ajoutez le nombre de tâches restantes.
+- Modifiez le code pour que les tâches soient stockées localement (utilisez l'objet `localStorage`).
