# Deno vs. Node

[Deno](https://deno.land) improves upon [Node.js](https://nodejs.org) in some significant ways.

### Modules

Modules are loaded directly from URLs and cached locally.

```js
import confetti from "https://esm.sh/canvas-confetti@1.6.0";
```

This allows the decentralization of packages by removing reliance on [npm](https://npmjs.com) and enabling developers to self-host their packages.

Consequently, this removes the need for `package.json` and `node_modules`, and allows programs to run in the browser since there is no reliance on build tools like Webpack.

### Security

Because code is executed in a sandbox, the Deno runtime has no access to the file system and the network. Flags like `--allow-write` and `--allow-net` can be used to explicitly enable access.

In addition to the above features, Deno supports TypeScript out of the box and has a built-in formatter for code similar to ESLint for Node.js.
