TOP 10 Groovy Closure usage examples - users choice

The story

A couple of months ago, I asked Groovy users on Twitter about their favorite example of using Groovy closures. My goal was to collect some data, process it, and write a blog post. Unfortunatelly, it never happened.

18 people answered to my tweet and shared many interesting examples. I couldn't waste so many useful data, and that is why a few days ago I decided to do something with it.

The solution

Instead of writing a blog post, I thought I will record a short video where I can show all examples in the IDE and add some commentary to it.
