It is not the same as that. the fat arrow doesn't change the value of "this" while the function definition does.

  Given that "this" isn't referenced in the function, though, it's practically equivalent.

    I think one is more efficient memory wise but I'm not sure which one.

      The non-fat-arrow one, as it does not need to carry around the context of `this` with it.

        Do you have a reference for this? I always thought arrows were lighter weight because their `this` is static rather than dynamic.
