Deno is a modern, open-source JavaScript runtime built in Rust by the original creator of Node.js.
Install Deno with a single command and use `deno init` to scaffold a new project with essential files.
Install the official Deno VS Code extension to enable the Language Server Protocol for features like auto-completion and error highlighting.
Run tests without third-party dependencies using the built-in `deno test` command and assertion libraries from the standard library or JSR.
Leverage the Deno standard library for common tasks and manage project dependencies and scripts within the `deno.json` configuration file.
Deno uses a global cache instead of a `node_modules` folder and includes built-in tools for type checking, linting, and formatting.
Interact with the file system, create a basic HTTP server with `Deno.serve`, and use standard web APIs like `fetch` directly in the runtime.
Use Node.js built-in modules via the `node:` specifier and manage runtime access to sensitive APIs through Deno's explicit permission model.
Run an existing Node.js application in Deno by using `deno install` to handle dependencies and executing its scripts from `package.json`.
