If you want to start to develop solutions with Azure Functions, you have to know one of the languages Azure Functions supports (at this moment in time, C#, JavaScript, Java, and Python). If you do, you'll easily be able to follow this book.
The Microsoft entry point for the Azure Functions documentation is located at https://azure.microsoft.com/en-us/services/functions/. Starting from there, you can find technical documentation, whitepapers, and samples, and you can navigate to the GitHub repositories for the different tools you'll encounter in this book.
Finally, you can find the source code for this book at https://github.com/PacktPublishing/Mastering-Azure-Serverless-Computing/tree/master/Chapter01.
