• Arrow functions do not have an arguments binding. But they have access to the arguments object of the closest non-arrow parent function. Named and rest parameters are heavily relied upon to capture the arguments passed to arrow functions.

function dummy() {
  return (() => arguments.callee.name)(); // dummy
}

• The value of this inside an arrow function remains the same throughout the lifecycle of the function and is bound to the value of the closest this-providing environment.

const obj = {
  // like a normal function, returns obj - defines like obj.a = function a() {};
  a() { return this },
  // arrow function uses global as this
  b: () => { return this },
};
console.log(obj.a() == obj) // true
console.log(obj.b() == obj) // false
console.log(obj.b() == window) // true

• Arrow functions can never be used as constructor functions. Hence, they can never be invoked with the new keyword. As such, a prototype property does not exist for an arrow function.

Therefor, the only way to get the name of an arrow function is from accessing the direct reference to it.

const arrow = () => arrow.name;
console.log(arrow()); // "arrow"

const obj = {
  a: () => obj.a.name;
}
console.log(obj.a()); // "a"
