Welcome to Deno!Well,
Here is another example.
deno can execute a local index.js / index.ts just as Node.js can. However, it is notable that deno doesn't create package.json, package-lock.json and even node_modules directory!Here is another example.
$ mkdir my-first-deno
$ cd my-first-deno
$ touch index.js # or index.tsAdd the line to
index.js:console.log('Hello, world.');You can run it:
$ deno run index.js
Hello, world.44
