I have read some of the documentations regarding modern js and ES6 and how to implement package manager with the existing code of javascript with ES5 to be working with ES6.

Also I have read about some of the js testing libraries which can be used to ensure that the js code is written properly with unit testing defined for functions.

I have also found one issue on which I would like to contribute but I am facing some of the problems in building the code.

So kindly help me in this regard.
