 Some would argue, at least in some circumstances, yes. But I think an equal argument can be made of many other circumstances that here, the simplification **actually aids in the readability of the code** by abstracting or hiding away such details, either in the language itself or in our own abstractions.
 
-Undoubtedly, behind the scenes, somewhere, the intermediate conversion step is still happening. But if that detail is hidden from view here, we can just reason about getting `y` to type `SomeType` as an generic operation and hide the messy details.

 While not a perfect analogy, what I'm going to argue throughout the rest of this chapter is that JS *implicit* coercion can be thought of as providing a similar aid to your code.
