Discover the essential differences between Deno and Node.js with this beginner-friendly quiz. Review key features, security, compatibility, and runtime behavior to deepen your understanding of modern JavaScript runtimes.
Which runtime restricts file, network, and environment access by default unless specific permissions are granted?
Explanation: Deno is designed to be secure by default, denying file, network, and environment access unless explicit permissions are set. Node.js, in contrast, allows such access without additional configuration. 'Nodje' and 'Denox' are not actual runtimes; their inclusion serves to check attention to detail.
Which runtime uses URLs and the standard fetch command to load modules instead of a built-in package manager?
Explanation: Deno imports modules directly from URLs, utilizing browser-style imports, and does not use a built-in package manager. Node.js relies on a package manager, typically with a package.json file, for handling dependencies. 'Nodejs' and 'Denio' are incorrect variations and not actual tools.
Which runtime supports TypeScript code out of the box, allowing you to run TypeScript files without extra configuration?
Explanation: Deno natively supports TypeScript, allowing direct execution of .ts files without manual setup. Node.js, by default, supports only JavaScript and requires additional tools to run TypeScript. 'Dine' and 'Notede' are not JavaScript runtimes.
Which runtime was created to prioritize compatibility with existing JavaScript tools and packages in its initial design?
Explanation: Node.js was built to support the rapid development of tools and packages, resulting in a vast ecosystem aligned with previous JavaScript standards. Deno intentionally breaks some conventions for improved security and functionality. 'Dano' and 'Nodo' are distractors and do not refer to real runtimes.
Which runtime does not require a centralized package.json file to manage modules or scripts?
Explanation: Deno handles dependencies directly through imported URLs, so there is no need for a package.json configuration file. Node.js depends on package.json for dependency and script management. 'Nodejx' and 'Donu' are not actual runtimes; they are included as plausible-sounding options.
Which runtime provides built-in utilities for testing, linting, and formatting code without installing extra modules?
Explanation: Deno includes a suite of built-in tools for testing, linting, and formatting, promoting an all-in-one development experience. Node.js users typically rely on external packages for these features. 'Denno' and 'Nodeno' are not real tools, included as distractors.
Which runtime natively supports ECMAScript module syntax, such as import and export statements, with no extra setup?
Explanation: Deno fully adopts ECMAScript’s module syntax, making import and export statements work out of the box. Node.js traditionally used its own module system and added ECMAScript module support later with some configuration. 'Nodeos' and 'Denojs' are not actual runtimes.
Which runtime encourages using .ts and .js files with modern module imports by default and warns if a file extension is missing?
Explanation: Deno requires explicit file extensions in module imports and supports both .ts and .js natively, enforcing clarity. Node.js can infer extensions under certain conditions and historically did not require strict extension usage. 'Demos' and 'Dene' serve as realistic typographical distractors.
Which runtime uses command-line flags like --allow-net or --allow-read to grant specific permissions to programs?
Explanation: Deno operates under a security sandbox system that restricts operations unless specific flags are set, such as --allow-net for network access. Node.js permits access without such flags by default. 'Denoe' and 'Noden' are distractors mimicking real names.
Which runtime is known for full compatibility with npm packages out of the box, supporting a wide variety of third-party modules?
Explanation: Node.js offers seamless compatibility with npm and a huge ecosystem of third-party modules. Deno can use modules from URLs but does not natively support npm packages without extra steps. 'Nodex' and 'Deeno' are not recognized runtimes.
