Answer 3

There is no readLine function in javascript .

You need to call main function as well.

i believe sololearn code coaches for node js are programmed differently to help them with processing user input.

Answer 4

Egor Tonchev(EGO) i only know of this readline module.

But for sure the readLine function will still work here on sololearn as i said i believe they use it to process user inputs in a different way , just not idea what they do exactly.
