How can I turn numeric values into categories?.Is there a way I can handle null values in my popups?.Why isn’t the newline text formatting showing up on my labels?.What’s the best way to debug an Arcade expression?.What does this mean exactly? Do I need to have one? I see something about “returns” in the documentation and examples.
Will my map show those changes if I use Arcade?
My data changes behind-the-scenes regularly. Can I reuse an expression I’ve already written?. What is an expression? What does it do?. Where do I find Arcade? How can I use it?. Do I have to own a layer to use Arcade?. Does Arcade change the underlying data table?. You can also find the official ArcGIS Arcade FAQ here, which contains some of the same questions. Feel free to use this resource if you are just getting started with Arcade, or if you are familiar with Arcade and have some nagging questions. In this article, my colleague Gee Fe rnando from Esri Australia and I offer easy-to-understand answers and examples to the questions we get the most. While there are blogs, ArcGIS Learn resources, and documentation pages to get you started, not everyone has the time to spend on tutorials. This made me realize that many people might have similar questions, so a ton of my Arcade wizard teammates and I compiled the most common questions we get about Arcade. 
I regularly get questions about Arcade and what it can do. If you are, however, a coding wizard, A rcade is a powerful way to enhance your maps in new ways. What is incredible, is that y ou don’t have to be a “coder” to do amazing things with Arcade. For those who have used it, t here’ s no secret that it is changing the way people make their maps and work with data. ArcGIS Arcade was introduced to the ArcGIS platform back in 2016 but is somewhat of a hidden gem.
