One of the big reasons for going with Deno is that it's an open runtime closely based on web standards. You can download the open source Deno Cli and all code written for our edge layer will run exactly the same there.

As more and more front-end frameworks starts leaning in on running part of their code at the edge, we felt it was important to champion and open, portable runtime for this layer vs a proprietary runtime tied to a specific platform.
