Bun uses WebKit's JavaScriptCore as the JavaScript engine, [6] unlike Node.js and Deno, which both use V8. It supports bundling, minifying , server-side rendering ( Svelte , Nuxt.js , Vite ). Bundling refers to the process of combining multiple files and assets like JavaScript , CSS , and HTML into a single file, or a smaller number of files ...
Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine , and executes JavaScript code outside a web browser .
In batch mode, non-existent environment variables are replaced by a zero-length string. Standard environment variables or reserved environment variables include: %APPEND% (supported since DOS 3.3) This variable contains a semicolon-delimited list of directories in which to search for files.

It is used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment. Using env, variables may be added or removed, and existing variables may be changed by assigning new values to them.
The Node-RED project has a number of components: Node-RED, the visual designer tool. Node-RED Dashboard, a dashboard user interface for Node-RED.; Node generator, a command-line tool to generate Node-RED node modules from several sources, including OpenAPI documents and a function node's source.
The development environment then returns to the read state, creating a loop, which terminates when the program is closed. REPLs facilitate exploratory programming and debugging because the programmer can inspect the printed result before deciding what expression to provide for the next read. The read–eval–print loop involves the programmer ...
Deno and Node.js are both runtimes built on the V8 JavaScript engine developed by the Chromium Project, the engine used for Chromium and Google Chrome web browsers. They both have internal event loops and provide command-line interfaces for running scripts and a wide range of system utilities. Deno mainly deviates from Node.js in the following ...
In Linux, the file specified by interpreter can be executed if it has the execute rights and is one of the following: a native executable, such as an ELF binary; any kind of file for which an interpreter was registered via the binfmt_misc mechanism (such as for executing Microsoft .exe binaries using wine) another script starting with a shebang
