# Lab Exercises

Welcome to the lab exercises repo! 

Here you'll find all the example code which accompanies weeks 1-10 of **Data, Networks & the Web**. The example code is for a music store app, so you will need to adapt it for whatever app you're developing. Remember to comment the code to show your understanding.
