QUESTION

What was the motivation for introducing a separate microtask queue which the event loop prioritises over the task queue?

Asked 2021-Feb-26 at 14:27

My understanding of how asynchronous tasks are scheduled in JS

Please do correct me if I'm wrong about anything:

The JS runtime engine agents are driven by an event loop, which collects any user and other events, enqueuing tasks to handle each callback.

The event loop runs continuously and has the following thought process:

Is the execution context stack (commonly referred to as the call stack) empty?
If it is, then insert any microtasks in the microtask queue (or job queue) into the call stack. Keep doing this until the microtask queue is empty.
If microtask queue is empty, then insert the oldest task from the task queue (or callback queue) into the call stack

So there are two key differences b/w how tasks and microtasks are handled:

Microtasks (e.g. promises use microtask queue to run their callbacks) are prioritised over tasks (e.g. callbacks from othe web APIs such as setTimeout)
Additionally, all microtasks are completed before any other event handling or rendering or any other task takes place. Thus, the application environment is basically the same between microtasks.

Promises were introduced in ES6 2015. I assume the microtask queue was also introduced in ES6.

My question

What was the motivation for introducing the microtask queue? Why not just keep using the task queue for promises as well?

Update #1 - I'm looking for a definite historical reason(s) for this change to the spec - i.e. what was the problem it was designed to solve, rather than an opinionated answer about the benefits of the microtask queue.

One advantage is fewer possible differences in observable behavior between implementations.

If these queues weren't categorized, then there would be undefined behavior when determining how to order a setTimeout(..., 0) callback vs. a promise.then(...) callback strictly according to the specification.

I would argue that the choice of categorizing these queues into microtasks and "macro" tasks decreases the kinds of bugs possible due to race conditions in asynchronicity.

This benefit appeals particularly to JavaScript library developers, whose goal is generally to produce highly optimized code while maintaining consistent observable behavior across engines.

QUESTION

Convert Firefox bookmarks JSON file to markdown

Asked 2020-Dec-08 at 16:10

Background

I want to show part of my bookmarks on my Hugo website. The bookmarks from Firefox can be saved in JSON format, this is the source. The result should represent the nested structure somehow, in a format of a nested list, treeview or accordion. The source files of contents on the website are written in markdown. I want to generate a markdown file from the JSON input.

As I searched for possible solutions:

treeview or accordion: HTML, CSS and Javascript needed. I could not nest accordions with the tag. Also, seems like overkill at the moment.
unordered list: can be done with bare markdown.

I chose to generate an unordered nested list from JSON. I would like to do this with R.

Answered 2020-Dec-08 at 16:10

After I watched a few videos on recursion and saw a few code examples, I tried, manually stepped through the code and somehow managed to do it with recursion. This solution is independent on the nestedness of the bookmarks, therefore a generalized solution for everyone.

Note: all the bookmarks were in the Bookmarks Toolbar in Firefox. This is highlighted in the generate_md function. You can tackle with it there. If I improve the answer later, I will make it more general.

ANSWER

Answered 2020-May-10 at 06:34

This has got nothing to do with material-ui, you've applied marginLeft: auto, which will not apply marginRight: auto, so it would not be center aligned

you should add marginRight: auto, as well to center it.

React, using Hooks to create component

Asked 2020-Apr-26 at 10:04

I am trying to use a hook to create a textbox that provides the value state as part of the hook.

However, I am not quite successful, as the textbox keeps losing focus whenever I tried to type.

This probably makes more sense if I show what I am doing.

Please see this Codepen for a quick demo. (https://codepen.io/david_yau/pen/RwWVoKz?editors=1111)

ANSWER

Answered 2020-Apr-26 at 10:04

Because const TextBox = () => will create a different React component every time useTextBoxTwo() is called, while const TextBox = is just a React element, rendered in the same Component (in App).

In the current implementation, when the element inside a component changes, ReactDOM checks whether it has the same element name (e.g. "input") and doesn't have a different key - when true, it re-uses the same DOM element, e.g. following 2 React-elements will reuse the same DOM-element (not losing focus):

You are trying to export in useEffect function. I think you missed to close it. And also you close requestPets before useEFfect which is not also correct. I suggest you use eslint.

What are good resources to learn HTTP protocol?

Asked 2019-Oct-28 at 12:09

Nowadays, I'm reading Front-End Developer Handbook. Because I want to be successfull front-end developer. I've read Coderbyte's guide. There is also an HTTP suggestion in the article.

I researched for HTTP resources. i've found these links:

https://developer.mozilla.org/en-US/docs/Web/HTTP

http://httpwg.org/specs/

https://httpstatuses.com/

https://code.tutsplus.com/tutorials/http-the-protocol-every-web-developer-must-know-part-2--net-31155

^{Disclaimer: Don't be surprised if this question gets closed. Asking for this kind of resources is off topic here. I would post it a comment, but the content wouldn't fit well, hence I'm posting it as an answer.}

RFCs

The RFC's 7230-35 are the official references for the HTTP/1.1 protocol and these document define how HTTP is supposed to work:

RFC 7230: Message Syntax and Routing
RFC 7231: Semantics and Content
RFC 7232: Conditional Requests
RFC 7233: Range Requests
RFC 7234: Caching
RFC 7235: Authentication

For the HTTP/2 protocol, consider the following RFCs:

RFC 7540: Hypertext Transfer Protocol Version 2 (HTTP/2)
RFC 7541: HPACK: Header Compression for HTTP/2

It is worthwhile to mention that documents such as RFC 1945, RFC 2068, RFC 2616 and RFC 2617 are obsoleted and must not be used as reference anymore.

Mozilla Developer Network web docs

The MDN web docs about HTTP is also a credible source.

QUESTION

Why clearInterval is not working in my script?

Asked 2019-Apr-14 at 16:59

I have got a problem with my clearInterval method. I learn about JS in depth at FrontendMasters and there is an exercise where you need to use setInterval and log a string at every second and then run clearInterval after 5 seconds. I have access to the right solution but I would like to know why my solution is not working to get better understanding. The console.log('clear called', func); runs after 5 seconds and log the clear called string and the function body. I have tried to use setTimeout to wrap wrapper.stop() but it did not work that way either. I have used closures to try to solve the exercise. Here is my script.

...

ANSWER

Answered 2019-Apr-14 at 16:59

clearInterval does not take a function but a timer id which gets returned when using setInterval (so that you can set multiple timers onto the same function, and cancel them individually). To use that, declare a local variable inside everyXsecsForYsecs
