 Arrow functions don't just make the code shorter. They are closely related to `this` binding behavior.
 
-Arrow functions behavior with `this` keyword varies from that of normal functions. Each function in JavaScript defines its own `this` context but Arrow functions capture the `this` value of the enclosing context. Check out the following code:
