I'm the old _require_ dog, so it comes at no surprise that I'm not happy with
https://docs.deno.com/runtime/fundamentals/modules/
_import_ favorizes large libraries, with _require_ I got used to library atomization.
Eventually I'll find my ways for optimal structuring of my libraries, but for now...
#ecmascript modules, #typescript and #deno don't make me happy.

I know it pays no bills but I love reading the #ECMAScript #Spec, so well written.
I am just exploring what an object is, https://tc39.es/ecma262/#sec-object-type
I can only encourage to read it, it's not hard to understand and it teaches a lot.

And if you would pay me for doing that I am in. Let me know.

The #deno docs are pretty danged good! I love the https://docs.deno.com/examples/ page. Reminds of the old O'Reilly "Cookbook" books with tons of short examples on how to do a specific thing without much fuss. Nice. #programming #webdevelopment #javascript #typescript #ecmascript #development #developers
