I don't quite understand why variables are followed by a "=>". Can't they be accessed globally?
What is the purpose of this: "=>" ?
And why is it used here?
This are anonymous functions written as arrow functions. They were introduced in ES6 and have become really popular since because they are 'scope safe', compact and better to read.
