1)  Check if nodejs exists

     cmd > node -v

    O/P: v0.10.0

     cmd > where node

    This means that nodejs is already present in your system  (usually the case with Win10)

      cmd> echo %PATH%

     It will show the same path as in the previous output. We need to remove this reference from   PATH    reference.

2) Download  nodejs from here and install

3) Confirm the installation again by cmd > node -v

   O/P:

It will look almost like this:

7) check Jasmine version
  cmd >  npm view jasmine version
