The command "deno" is an executable that runs the Deno runtime environment. Deno is a secure JavaScript and TypeScript runtime built on the V8 JavaScript engine and the Rust programming language. It provides a secure and sandboxed environment for running JavaScript and TypeScript code.
When you execute the "deno" command, it launches the Deno runtime and allows you to run JavaScript or TypeScript files or execute specific Deno commands and options. For example, you can run a JavaScript file by passing the filename as an argument to the "deno" command:
deno myfile.js
You can also specify additional options or flags to control the behavior of the Deno runtime, such as enabling or disabling specific permissions or allowing network access. You can explore the available options and commands by running:
deno --help
This will display the help text with all the available options and commands supported by the Deno runtime.
