Notes for Post

Installing Deno

Deno is a secure JavaScript and TypeScript runtime (website), built by Ryan Dhal, the original developer of Node.js.

I wanted to write a small utility in Deno that covers some of the fundamental concepts I'd want to know in any programming language, so in this article, I'll be building a utility that fetches a Zip directory from Dropbox, writes it to disk and unzips the Zip into a directory.

First, I visited the Deno homepage to find the installation instructions page. Deno recommends a "curl | bash" script to install it using Shell (there is also a Homebrew formula for Mac and Linux).
