Running JavaScript from the command line without Node.js can be done using the built-in Windows Script Host (WSH) on Windows or other similar scripting environments available on different platforms. Here's how you can run JavaScript without Node.js:

Using Windows Script Host (WSH) on Windows:

Create a JavaScript File:
Create a .js file containing your JavaScript code. For example, create a file named myscript.js and add your JavaScript code to it.
Run the Script:
Open a command prompt and use the cscript command to run the JavaScript file with Windows Script Host.
```
batch
cscript myscript.js
```

Using JScript on Windows:

JScript is Microsoft's implementation of JavaScript. It's often available on Windows systems.

Create a JavaScript File:
Create a .js file containing your JavaScript code.
Run the Script:
Open a command prompt and use the jscript command to run the JavaScript file.
```
batch
jscript myscript.js
```

Using SpiderMonkey on Unix-like Systems:

SpiderMonkey is the JavaScript engine used in Mozilla Firefox. You can use the js command to run JavaScript files.

Create a JavaScript File:
Create a .js file containing your JavaScript code.
Run the Script:
Open a terminal and use the js command to run the JavaScript file.
```
bash
js myscript.js
```

Please note that these methods might have limitations compared to using a dedicated JavaScript runtime like Node.js. Additionally, the global objects and APIs available might differ between different JavaScript environments.

Keep in mind that the command-line environment varies between platforms, so the availability of these options might differ depending on the operating system you're using.
