[Reminder-2] Arrow Function

I am assuming you are using "use strict"

• Arrow function syntax is () => {}
• If you have one parameter you can delete parantheses.
• If you are doing one action, you can delete the curly braces. () => console.log("hi")
• It has an implicit return
• It create a new Scope as Normal function (watch my last reminder if you want more).
• It doesn't bind context like classic function. That means 'this' will never be bind and will be undefined or window.
• It cannot act as a constructor like normal function
