The command "coffee --interactive" is used to invoke the CoffeeScript REPL (Read-Evaluate-Print Loop) or interactive mode. CoffeeScript is a programming language that compiles into JavaScript.
When you run this command, it starts an interactive console that allows you to directly execute CoffeeScript code. You can type CoffeeScript code line by line, and the REPL will evaluate and execute it immediately. This can be useful for testing out small code snippets, experimenting with language features, or quickly prototyping ideas.
By entering the command, you enter an environment where you can interactively write and execute CoffeeScript code without the need to create a separate file or application. The output of each code snippet will be displayed immediately after execution, allowing you to see the result without the need to run a complete CoffeeScript program.
To exit the CoffeeScript interactive mode, you can use the "Ctrl + C" keyboard shortcut or type ".exit" in the REPL.
