You may want to clone the GitHub repository now with all of the examples contained in this book. You'll definitely need to have the code available for Chapter 7, Creating an Application from Scratch, because the application's code base is too large to fit into a single chapter. Select a folder on your hard drive and run the following command to clone the repository:
git clone https://github.com/mikerourke/learn-webassembly
Once the clone process is complete, you'll find that the examples are organized by chapter. If there are several examples in a chapter, they're broken down by subfolders within the chapter folder.
If you're using Windows, do not clone the repository into the Windows folder or any other folder with limited permissions. Otherwise, you will run into issues when attempting to compile the examples.
