Deno

Deno is an open-source runtime for JavaScript, TypeScript, and WebAssembly, designed with modern features and secure defaults. Key highlights include: 1. **Seamless Node.js Integration**: Deno can run Node.js projects, allowing a smooth migration. 2. **Modern Module System**: Utilizes ES modules and URL imports, supporting typed packages and workspaces. 3. **TypeScript First**: Allows direct execution of TypeScript files without a separate compilation step. 4. **Security**: Runs code in a sandbox environment; permissions must be explicitly granted for file, network, and environment access. 5. **Built-in Toolchain**: Includes a formatter, linter, test runner, and various utilities, eliminating the need for third-party dependencies. ### Getting Started - **Installation**: Simple installation via command line. - **Project Creation**: Use `deno init` to scaffold a new project that comes with configuration and basic files. - **Running Code**: Start your application with the `deno` command, specifying permissions. - **Testing**: Run built-in tests effortlessly with `deno test`. - **Adding Dependencies**: Integrate packages using `deno install`. - **Tool Usage**: Use built-in commands for formatting, linting, and task execution without additional setup. ### Next Steps Explore editor setup, advanced usage, dependency management, migration from Node.js, and available tutorials.
