How to use readLine() in Javascript

Question

I'm trying to solve the excercises in JavaScript, supposedly the input is already defined, but when I try to use that value, I simply can't do it, I wrote my code in an online compiler and says "Uncaught ReferenceError: readline isn't defined" and I don't know how to solve that error, I searched online but simply the error isn't fixed, please Help me

Answer 1

JavaScript do not have readLine() statement.
The tests will be prepared in node.js.

Answer 2

Jesús Emmanuel Justo González I suppose you are trying in NodeJS?

Martin Taylor JaScript

In lesson practices the test environment provides you a readLine() function, and also force you have a main() function

But in code playground it doesn't exists.

You need to read buffered and synchronous from process.stdin

or use the readline built-in module (callbacks/promises)

NOTE: Codes above are some of my experiments and therefore must be take as is, can have some bugs and of course, be improved.

Some usefull doc/libs outside SoloLearn:
