How do I get console input in javascript?

问题:

I'm currently using spidermonkey to run my JavaScript code. I'm wondering if there's a function to get input from the console similar to how Python does this:

var = raw_input()  

Or in C++:

std::cin >> var;

I've looked around and all I've found so far is how to get input from the browser using the prompt() and confirm() functions.

Good old readline();

See MDN docs: https://developer.mozilla.org/en-US/docs/Mozilla/Projects/SpiderMonkey/Introduction_to_the_JavaScript_shell#readline.28.29

In plain JavaScript, simply use response = readline() after printing a prompt.

In Node.js, you'll need to use the readline module: const readline = require('readline')
