The sentence "This An arrow function does not have its own this; the this value of the enclosing execution context is used" is misleading: "execution" should be changed to "lexical scope" instead (quote from: Kyle Simpson's "Scope & Closures", p. 77: [arrow functions] "take on the this value of their immediate lexical enclosing scope").
If an arrow function is created inside a function expression in a context "a", and then referenced and executed in a context "b", it maintains the "this" of the orignal context "a".
Priority: P5 → P2
