As far as I know, there is a readline() function, but it is a specific function for spidermonkey, it isn't a part of javascript.
Example:
1)readline-test.js:
print("Type some text and press <ENTER>:\t");
var userInput = readline();
print("User input: " + userInput);
2)js readline-test.js
For more information see https://developer.mozilla.org/en-US/docs/SpiderMonkey/Introduction_to_the_JavaScript_shell.

@SwapnaLekshmanan could you please point to the documentation where it is said about capital L? Doc at the link I have provided state that a proper function name is 'readline()' (lower case)

@SwapnaLekshmanan, I've double-checked and reverted you changes to 'readline()'.
You can't really depend on the console being there. It's not something that is guaranteed, even while most browsers do have a javascript console. Beyond that I don't believe you can get values without calling a function with the console.
