Evangelization is "preaching"; it's essentially advertising or marketing.
There's no one way to preach or advertise. One can take a number of different approaches. Presenting technical information is one way, the most common way. It's how most languages are promoted. But most languages never succeed with this approach. Most languages never gain much mind share.
So the author has taken another approach, something that is seldom attempted. The programming competition is an original and clever idea.
I'm not sure how one can "demonstrate the benefits" of a programming language. Most languages have been used successfully in software projects (e.g., Crystal, Elixir, F#, Haxe, Julia, Nim, etc.). Does trotting out these projects prove anything?
