• by using npm, we are instructing the package manager to download the protractor package.
• g stands for global. So this protractor will be available globally.
• This will be installed at the AppData path C:\Users\Biswajit\AppData\Roaming\npm\node_modules
• Go to command prompt and type protractor --version, it should return the version like 7.0.0
