Preface

What’s in a Name?

This book has been written at a time when the Spark organization was rebranding itself as Particle. As a result of this, you will find that some of the screenshots have the old company name, as they were taken before the new web interface became available. You will also find that the code for this book uses class names and third-party code libraries that still show the Spark name. These are set to work in the short term, but when they eventually become deprecated, watch for information on these changes at the Particle website.
