To get the most out of this book
You don't need to have full knowledge of the Ballerina programming language to follow the samples given here. But you should have a basic understanding of at least one general-purpose programming language, such as Java, C, or Go, since Ballerina syntax is very similar to those.
The samples given in this book are tested on macOS. These samples should also work with Linux and Windows operating systems as well. The tools and libraries used in this book are free and open source. You can try out all of these samples free of charge. But the samples given in iPaaS and Software as a Service (SaaS) platforms such as AWS, Azure, Choreo, and Snowflake may charge you based on usage of the resources.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
