Does arrow syntax the same as function?

Is the arrow syntax just a simplified(cleaner) way to write a function? Andrew doesn't really explain it very well here.

It is a cleaner way to from a function but it also has implications in object oriented JavaScript as it changes the this keyword context. When you normally write a method (function) in an object the "this" keyword called inside that method refers to the window object, however when you call the "this" keyword from inside a method that uses the arrow syntax "this" refers to the object that the method is inside.
