"Exploring The QGIS Expression Engine, Part 5: Fun With Arrays"
A short post with some examples about what you can achieve by using some new and some old array functions in the QGIS expression engine.

Arrays and the functions that handle them allow us to expand our abilities with QGIS expressions and perform more complex selections, as well as better ways to visualize our data and in some ways create new geometry.

This was supposed to be the third post in the QGIS expression engine series but turned out fifth. It also came out a bit shorter than expected since I moved some of the more complex expressions to the next post which will receive its own post.
