Why they haven’t provided code in Javascript when it’s under JS module.
Is it advisable to code this in C++ in interview ?

Hi @Madhav, Thanks for reaching out to us.
The given solution is just for the implementation purpose that’s why it can be in any programming language. You can implement it in any other language like Javascript according to your ease. Secondly, this course is designed for grokking the Object Oriented Design Interview so you can go through it for your C++ interview as well.
Hope you will understand, Happy Learning 
@Muntha_Amjad If anyone already knows how to implement in JS then why would they consider purchasing it and going through this course…
