Why doesn't parseInt(readLine()) work in VS code but works in sololearn JS console?

Question

I tried the following code in VScode
var m = parseInt(readLine(),10);
And it returned readLine is not defined.
After some research I first added the line:
const readLine = require('readline');
And now VScode terminal shows error readLine is not a function because it's a class. Why doesn't it work in VScode. Also how else to take the input from user in VScode?

Answer 1

VS is only an editor.

readLine is a function used by sololearn to get user input.

Maybe you can use prompt().

Answer 2

You have to import the readline module beforehand in Nodejs Application & also, it is an async function which takes object as an argument.

readline.createInterface({ input, output });

Well, I admit, I don't know how sololearn handles input or node.js. I hypothesized it would be related to node.js as in the sololearn course they always use node.js playground scripts for user input (instead of the usual web script)...

I edited my initial comment. Maybe someone finds this thread helpful:
