I’ve started learning about Deno.
For example, load Rambda (the smaller alternative to the functional programming library Ramda):
import * as R from 'https://unpkg.com/rambda@^5.6.1/dist/rambda.esm.js'
Deno also offers tons of functionality out of the box, e.g., logging or testing.
First-class TypeScript support is nice, because you don’t have to bother with setting up TypeScript.
