            Is it safe to store, access and HTMLElement objects directly inside an object, vs. relying on CSS selectors?
            Asked 2022-Jan-22 at 09:00

            I have a vanilla Javascript class that builds a bunch of HTML, essentially a collection of related HTMLElement objects that form the user interface for a component, and appends them to the HTML document. The class implements controller logic, responding to events, mutating some of the HTMLElements etc.

            My gut instinct (coming from more backend development experience) is to store those HTMLElement objects inside my class, whether inside a key/value object or in an array, so my class can just access them directly through native properties whenever it's doing something with them. But everything I look at seems to follow the pattern of relying on document selectors (document.getElementById, getElementsByClassName, etc etc). I understand the general utility of that approach but it feels weird to have a class that creates objects, discards its own references to them, and then just looks them back up again when needed.

            A simplified example would look like this:

            In general, you should always cache DOM elements when they're needed later, were you using OOP or not. DOM is huge, and fetching elements continuously from it is really time-consuming. This stands for the properties of the elements too. Creating a JS variable or a property to an object is cheap, and accessing it later is lightning-fast compared to DOM queries.

            Many of the properties of the elements are deep in the prototype chain, they're often getters, which might execute a lot of hidden DOM traversing, and reading specific DOM values forces layout recalculation in the middle of JS execution. All this makes DOM usage slow. Instead, create a simplified JavaScript model of the page, and store all the needed elements and values to the model whenever possible.

            A big part of OOP is just keeping up states, that's the key of the model too. In the model you keep up the state of the view, and access the DOM only when you need to change the view. Such a model will prevent a lot of "layout trashing", and it allows you to bind data to elements without actually revealing it in the global namespace (ex. Map object is a great tool for this). Nothing beats good encapsulation when you've security concerns, it's an effective way ex. to prevent self-XSS. Additionally, a good model is reusable, you can use it where ever the functionality is needed, the end-user just parametrizes the model when taken into use. That way the model is almost independent from the used markup too, and can also be developed independently (see also Separation of concerns).

            A caveat of storing DOM elements into object properties (or into JS variables in general) is, that it's an easy way to create memory leaks. Such model objects are usually having long life-time, and if elements are removed from the DOM, the references from the object have to be deleted as well in order to get the removed elements being garbage-collected.

            In practice this means, that you've to provide methods for removing elements, and only those methods should be used to delete elements. Additionally to the element removal, the methods should update the model object, and remove all the unused element references from the object.

            It's notable, that when having methods handling existing elements, and specifically when creating new elements, it's easy to create variables which are stored in closures. When such a stored variable contains references to elements, they can't be removed from the memory even with the aforementioned removing methods. The only way is to avoid creating these closures from the beginning, which might be a bit easier with OOP compared to other paradigms (by avoiding variables and creating the elements directly to the properties of the objects).

            As a sidenote, document.getElementsBy* methods are the worst possible way to get references to DOM elements. The idea of the live collection of the elements sounds nice, but the way how those are implemented, ruins the good idea.

            What is non-blocking or asynchronous I/O in Node.js?

            the description sounds no different from the event loop in vanilla js. Is there a difference between the two? If not, is the Event loop simply re-branded as "Asynchronous non-blocking I/O" to sell Node.js over other options more easily?

            ...

            ANSWER

            Answered 2021-Dec-10 at 06:41

            There are 2 different Event Loops:

            1. Browser Event Loop
            2. NodeJS Event Loop
            Browser Event Loop

            The Event Loop is a process that runs continually, executing any task queued. It has multiple task sources which guarantees execution order within that source, but the Browser gets to pick which source to take a task from on each turn of the loop. This allows Browser to give preference to performance sensitive tasks such as user-input.

            There are a few different steps that Browser Event Loop checks continuously:

            • Task Queue - There can be multiple task queues. Browser can execute queues in any order they like. Tasks in the same queue must be executed in the order they arrived, first in - first out. Tasks execute in order, and the Browser may render between tasks. Task from the same source must go in the same queue. The important thing is that task is going to run from start to finish. After each task, Event Loop will go to Microtask Queue and do all tasks from there.

            • Microtasks Queue - The microtask queue is processed at the end of each task. Any additional microtasks queued during during microtasks are added to the end of the queue and are also processed.

            • Animation Callback Queue - The animation callback queue is processed before pixels repaint. All animation tasks from the queue will be processed, but any additional animation tasks queued during animation tasks will be scheduled for the next frame.

            • Rendering Pipeline - In this step, rendering will happen. The Browser gets to decide when to do this and it tried to be as efficient as possible. The rendering steps only happen if there is something actually worth updating. The majority of screens update at a set frequency, in most cases 60 times a second (60Hz). So, if we would change page style 1000 times a second, rendering steps would not get processed 1000 times a second, but instead it would synchronize itself with the display and only render up to a frequency display is capable of.

            Important thing to mention are Web APIs, that are effectively threads. So, for example setTimeout() is an API provided to us by Browser. When you call setTimeout() Web API would take over and process it, and it will return the result to the main thread as a new task in a task queue.

            The best video I found that describes how Event Loops works is this one. It helped me a lot when I was investigating how Event Loop works. Another great videos are this one and this one. You should definitely check all of them.

            NodeJS Event Loop

            NodeJS Event Loop allows NodeJS to perform non-blocking operations by offloading operation to the system kernel whenever possible. Most modern kernels are multi-threaded and they can perform multiple operations in the background. When one of these operations completes, the kernel tells NodeJS.

            Library that provides the Event Loop to NodeJS is called Libuv. It will by default create something called Thread Pool with 4 threads to offload asynchronous work to. If you want, you can also change the number of threads in the Thread Pool.

            NodeJS Event Loop goes through different phases:

            • timers - this phase executes callbacks scheduled by setTimeout() and setInterval().

            • pending callbacks - executes I/O callbacks deferred to the next loop iteration.

            • idle, prepare - only used internally.

            • poll - retrieve new I/O events; execute I/O related callbacks (almost all with the exception of close callbacks, the ones scheduled by timers, and setImmediate()) Node will block here when appropriate.

            • check - setImmediate() callbacks are invoked here.

            • close callbacks - some close callbacks, e.g. socket.on('close', ...).

            Between each run of the event loop, Node.js checks if it is waiting for any asynchronous I/O or timers and shuts down cleanly if there are not any.

            In Browser, we had Web APIs. In NodeJS, we have C++ APIs with the same rule.

            I found this video to be useful if you want to check for more information.

            The main problem here is that checkboxes is not directly dependent on state (the only time a checkbox is related to state is when a it is initialised with isChecked: state[id]).

            This means that even though your state variable updates correctly when a checkbox is clicked, this will not be reflected on the checkbox itself.

            The quickest fix here would be to amend the JSX returned by your component so as to directly infer the isChecked property for the checkboxes from the current state:
