how $(this) in function and $(this) in () => {} are different?

I was debugging code, i found that $(this) inside function(event) refers actual element i.e. event.target but $(this) inside arrow function i.e. (event) => {} refers to the whole document. Can someone please help why this is there and what to do to make $(this) in arrow function to refer event.target.

Unlike conventional functions, arrow functions don't establish a "this". But event handlers are always passed an event object as a parameter, so you can use that instead:

var eventHandler = e => {
  // use "e.target" the way you previous used "this" in a conventional function
}
