Snippet from Wikipedia: Deno (software): Deno () is a runtime for JavaScript, TypeScript, and WebAssembly that is based on the V8 JavaScript engine and the Rust programming language. Deno was co-created by Ryan Dahl, the creator of Node.js and Bert Belder.
Deno explicitly takes on the role of both runtime and package manager within a single executable, rather than requiring a separate package-management program.

Provide a Deno glossary of the top 40 Deno concepts sorted by the most commonly used. For each concept include a brief description and the URL for the Deno official documentation. Answer using MediaWiki format.

Creating a glossary for the top 40 Deno concepts, along with descriptions and links to their official documentation, provides a comprehensive overview of Deno’s features and functionalities. Deno is a secure runtime for JavaScript and TypeScript that aims to address some of the shortcomings of Node.js, particularly around security, module management, and build simplicity. Here's a structured glossary in MediaWiki format covering fundamental to advanced Deno concepts, based on their commonality of use.

Simple Deno Glossary

This glossary outlines essential Deno concepts, providing users with a foundational understanding of Deno's features, along with links to the official documentation for further exploration.

Deno Runtime

The core runtime environment for executing JavaScript and TypeScript code outside of a web browser, focusing on security and efficiency. ; Official Documentation

TypeScript Support

Deno provides first-class support for TypeScript without requiring additional tooling, compiling TypeScript to JavaScript internally. ; Official Documentation

Security Model

Deno's security model is designed to run code in a secure sandbox, requiring explicit permissions for system access, network access, file operations, and more. ; Official Documentation

Modules

Deno uses ES modules as its module system and does not use `node_modules` or a package manager like `npm`. Modules are imported directly via URLs. ; Official Documentation

URL Imports

In Deno, you can import modules directly from URLs, which Deno fetches, caches, and compiles on the first run. ; Official Documentation

Deno Standard Library

A comprehensive standard library that is reviewed by the Deno core team, covering a wide range of functionalities, from date handling to HTTP utilities. ; Official Documentation

Deno CLI

The command-line interface for Deno, providing commands to run scripts, manage dependencies, and more. ; Official Documentation

Permissions API

Deno scripts can request or revoke permissions at runtime using Deno's Permissions API, offering a fine-grained security mechanism. ; Official Documentation

`deno run`

The command to execute a script with Deno, which may require flags to allow specific permissions. ; Official Documentation

`deno test`

A built-in testing utility that lets you define, run, and organize tests in a straightforward manner. ; Official Documentation

Dependency Management

Deno caches remote imports in a local cache, eliminating the need for a traditional package manager and improving performance and security. ; Official Documentation

`deno fmt`

Deno's built-in code formatter, ensuring consistent code style across your Deno projects. ; Official Documentation

`deno lint`

A linter for JavaScript and TypeScript code, helping to catch errors and enforce a uniform code style. ; Official Documentation

`deno compile`

Allows you to compile Deno projects into standalone executables, simplifying deployment and distribution. ; Official Documentation

`deno install`

Enables the installation of Deno scripts as executable commands on your system. ; Official Documentation

`deno doc`

A command-line tool for viewing documentation for Deno modules directly in the terminal. ; Official Documentation

`Deno` Global Object

A global object provided by Deno's runtime, offering various utilities, such as fetching resources, reading files, and managing permissions. ; Official Documentation

`import.meta`

Provides metadata about the module, such as its URL, which is particularly useful for modules fetched over the network. ; Official Documentation

Web Platform APIs

Deno aims to be browser-compatible where possible, supporting many Web Platform APIs like `fetch`, `WebSocket`, and `WindowOrWorkerGlobalScope`. ; Official Documentation

Async/Await

First-class support for asynchronous programming with Promises, async, and await, allowing for cleaner and more readable asynchronous code. ; Official Documentation

Workers

Deno supports web workers, enabling the execution of code in background threads for computational tasks or I/O operations that should not block the main thread

. ; Official Documentation

Deno Deploy

A globally distributed JavaScript runtime, optimized for minimal latency, which allows you to deploy Deno applications at the edge. ; Official Documentation

`deno bundle`

Combines JavaScript and TypeScript modules into a single script file, useful for packaging or distribution. ; Official Documentation

Top-Level Await

In Deno, you can use await at the top level in modules, eliminating the need for wrapping async calls in functions for initial execution. ; Official Documentation

Deno Language Server

An implementation of the language server protocol to provide enhanced editor integration for code completion, linting, and more. ; Official Documentation

Cross-Platform Support

Deno works across multiple platforms (Linux, macOS, and Windows) without significant changes to your code. ; Official Website

ES Module Support

Deno fully supports ECMAScript modules, making it compatible with modern JavaScript development practices. ; Official Documentation

First-Class Promises

Deno treats Promises as first-class citizens, with APIs designed to work seamlessly with asynchronous operations. ; Official Documentation

`deno upgrade`

Upgrades your Deno executable to the latest version, ensuring you have access to the most recent features and improvements. ; Official Documentation

Encrypted Communications

Deno supports HTTPS out of the box, allowing for secure communication with remote resources. ; Official Documentation

Native HTTP Server API

Deno includes a native API for creating HTTP servers, simplifying the process of building web applications and APIs. ; Official Documentation

`deno coverage`

A tool for collecting code coverage data from your tests, helping to identify untested parts of your code. ; Official Documentation

Import Maps

Deno supports import maps, allowing you to control and alias module imports without changing the source code. ; Official Documentation

Built-In Debugging

Deno integrates with Chrome DevTools for debugging, offering a powerful and familiar debugging experience. ; Official Documentation

TypeScript Configuration

While Deno supports TypeScript out of the box, you can customize the TypeScript compiler settings through configuration files. ; Official Documentation

This glossary introduces the core concepts of Deno, designed to provide a broad understanding of its capabilities and features. For a deeper dive into any of these topics, the official Deno documentation is an excellent resource. ```
