As you have progressed through the chapters of this book, you have seen how DAX code can increase in complexity as you have to solve more interesting analytical challenges. While there is nothing inherently wrong with intricate code structures that deliver a valid result, long and convoluted DAX measures can be both hard to write and even harder to debug and maintain.

So the developers of DAX have come up with an elegant solution to handling more advanced coding challenges. This is to use DAX variables. Variables in DAX
