Yep, and I think that determining `this` at the call-site is really awful, and has been the cause of many more bugs than is reasonable.
OOP you can do in JS with just `class` and `extends`, you no longer need to care too much about prototypes and how they work. Prototypes have become much more of an implementation detail in recent years.
That’s what almost all (more or less) dynamic languages do, except those that don’t have an arbitrary “object” struct. Out of few dynamic languages only python does what you need, at the cost of the enormous GC pressure. It’s okay for python because it was meant to be slow as hell by design.
And even then the solution would be more error-prone than the “issue” itself. Consider this code:
app.use(sass({
src: “.”,
log: console.log,
log2: function () {…},
}))
Your frustration is understandable, but I assure you that python’s “bound methods” are really awful to debug as well (been there done that), because the issue is not in functions taking “this” one way or another, but in a mismatch between developer’s expectations and reality.
I get around that in js mostly by avoiding classes and `this` entirely unless I'm sure I'm going to have a large number of instances of something. But there is the mental overhead of "Do I need to wrap this function in an arrow function before passing it around to avoid getting an unexpected `this`?"
So yeah, not saying I have a great solution -- just that none of the existing solutions really seem ideal.
First of all, it’s just a single-handed point of view. I’m using them from time to time, because js doesn’t end with reactjs hooks or frontend, and even frontend doesn’t end with just writing “frontend glueware”.
But even if it did, what exact mechanism do you propose to bind methods to instances? Automagic? It’s not just an “implementation detail”, it is a way of doing OOP in dynamic languages. Do you want all your objects to contain references to bound copies of all of the inherited methods? The way it is is for a reason, and the reason is, it doesn’t come for free.
