-------------------------------------------------------------
// The process object is a global that provides information about, 
// and control over, the current Node.js process. 
// As a global, it is always available to Node.js applications without using require().

// Instead of depending on process.argv property 
// we can use a third party node module called `yargv` as process.argv
// can be a bit messy.
