js-object | A macro for creating JavaScript objects in Rust | Reflection library

Since you're planning to save as JSON already, you can use its naturally recursive nature with its reviver parameter to return objects without the underscores. Map the entries of the object to a new object without the leading _.

Circular references are not bad in themselves. In particular, V8's garbage collection doesn't use reference counting (like, say, CPython), so if you're using JavaScript as implemented by V8, then circular references won't prevent garbage collection. There are some gotchas, though.

But circular references are only about the removability of objects. If you are destroying an element, you could remove all the references, which will definitely let them safely get garbage collected.

If you want to avoid expando properties, you could use a JavaScript Map to map from HTML elements to class instances. For example:

Yes, this is possible.

WebAssembly stores objects within linear memory, a contiguous array of bytes that the module can read and write to. The host environment (typically JavaScript within the web browser) can also read and write to linear memory, allowing it to access the objects that the WebAssembly modules stores there.

There are two challenges here:

1. How do you find where your WebAssembly module has stored an object?
2. How is the object encoded?

You need to ensure that you can read and write these objects from both the WebAssembly module and the JavaScript host.

I'd pick a known memory location, and a known serialisation format and use that to read/write from both sides.

Instead of manipulating the DOM manually, you can use Vue's conditional rendering to achieve the same goal. Take a look at this solution below:

ManuallyDrop does not stop the inner value from being destroyed. It only stops drop from being called. Consider a Vec:

You can't do this. Why not just

Using Array#reduce to build an Object with the collected data. Foreach object look in the accumulated object if there exists an prperty for this class. If not create one and add to this the groundstructure for this class. Afterwards add in both cases to the students array a new entry for this student.
After creating by this the object use Object#entries to take only the values of the object to get the ished array.

you can use ref for similar to querySelector reference in SFC.

Ok, post-edit I understand your question.

In a constructor function this is bound by the new operator to be the newly-created instance, there's no dynamic way to refer to the class itself like there is in a class static method:
