Edge Functions – completing the optimization stack
Edge Functions are small and lightweight pieces of code logic that are separate from your application code. Their name comes from the fact that they best perform on the edge (https://deno.com/blog/the-future-of-web-is-on-the-edge). Edge is a rather new term and refers to a paradigm of delivering a fast result by being as close to the executor as possible. That usually means that the piece of code that is supposed to execute is distributed to different server locations in the world.

Edge functions can be considered to be background workers. They need to be small and have a limited processing...
