I know JavaScript little but now to learn deno I have to learn first typescript which is a drag. Anyway deno just entered into market, so need of deno developer happens only in future. So wait until if this tech will change the world. Thanks for video.

Thanks for great video. I have installed the deno in windows and it's working in the installed directory. Can you please let me know how I can access that outside the installed directory? Need to set env variables?

Nice. Deno is what Node should have been from the start. IMO best things about Deno are browser API support and fact that you can just import stuff from online sources. Latter one means basically that community is not going to be wrapped inside, for example in Node's case, NPM. Also, Deno allows async code at top level, and that is not revolutionary at all, but it is common sense these days. There are probably few caveats right there, but nevertheless it is awesome feature.

npm isn't perfect by any means, but importing packages from live URLs seems like a cool feature rather than a practical one. What if the DNS gets spoofed?

Not sure how it is secure.
The modules are imported from the web directly.
If your app is in production and say the external dependency is no longer available, your app would break. Also if someone injects a malicious script in the external dependency when your app is in production, your app's security now is compromised.
