About the argument against it, "{@const will make code less consistent ": I think the same is true now, since people can come up with very different ways of dealing with the "computed value inside each loop/if function" problem. Some extract components, some use functions, some will prepare the array differently beforehand.

Also a vote against, for the simple reason that logicless templates would be the ultimate goal for me.

one of the reasons people sometimes balk at mustache-like syntax is just that: logic in the templates.

it also allows for more divergence in how people write there code and where they put their logic, making different svelte codebases potentially even more different due to fewer constraints. This last point is actually something I really value, I read a lot of Svelte code by a lot of different people and broadly speaking things look the same and are in the same places.

Our custom useEffect is not idiomatic Svelte.

We want to improve this while keeping both the API and the semantics and behavior as Reactish as possible.

For reasons of compatibility and simplicity, it's best to use React's built-in state management capabilities rather than external global state.

It provides several capabilities that are difficult to achieve with React alone, while being compatible with the newest features of React.

I’d still be interested in Svelte making things easier so I’ve opened a feature request for Reactive statement cleanup functions.

Svelte doesn't re-render, so you need to respond to component mount/dismount and prop changes separately as they are distinct concepts and never tied together, unlike in React.

Sometimes, you may be tempted to write that wrapper. Because all your (React or Vue or insert your reactive framework here) instincts tell you so.Resist the temptation. There is a better way. A svelter way. Introducing: the use-directive (a.k.a. “actions”).

However, especially when starting out, it’s very easy to fall into the “this is how I did things in my previous framework” trap.

It's sort of unfortunate that the justification for existence comes from pointing at gaps.

It was clear no one was interested in what I was working towards.

Although I also work with solid in my day job at inrupt, I wrote this guide in my spare time.

Built on TypeScript.

There's one downside to Reacts reactivity model - the hooks (useState and useEffect) have to always be called in the same order and you can't put them inside an if block.

createState and createSignal are improvements over React's useState as it doesn't depend on the order of calls.

import page from "//unpkg.com/page/page.mjs";

this is a common Svelte idiom for manually invalidating something that might have been mutated without there being a visible = sign somewhere

Because I haven't worked with React Native, and so I'm not a specialist in it, and developing a React Native version of this package would better be done by someone being an expert in React Native.

Graeber has a great deal more to say about money and its unique capacityto store value, and also about the ideology of the market with its highlyindividuated notion of human desires (e.g. 2001: 257). His analysis opensup an intriguing question. If in market societies money is a measure, amedium and above all an end in itself (2001: 66) and value-for-moneydominates what we conventionally call the economy, how do other valuescoexist with this monetarized realm and its rationality of quantificationand self-interest? Graeber points out that, in our view of society, marketprinciples can be balanced by family values and altruistic charity (2001:257), but he views these as just ‘two sides of the same false coin’

Only peer dependencies: Svelte and Final Form

t’s not clear why the sequence of the vaccines only mattered in girls, partly because there has been very little research into how male and female immune systems are different. “Somehow immunology has been blind to sex,” says Aaby. “If you read research about mortality in low income countries, there is no such thing as boys and girls – there are children. So we perceive that they have to be the same, and they are definitely not the same.”

It depends - do you accept the new code of conduct? :P

As you can see, it uses Javascript label syntax to tell the compiler where recalculation should be carefully managed. And you thought that no one uses labels any more.

It ends with love, exchange, fellowship

The benefit of this approach is that rather than having these defaults and fighting against them, it’s fully up to you to decide how to handle everything.

So I guess what @Rich-Harris is trying to say is that (sorry, I'm just logging it here for my own benefit)

Basically, the idea is that a train tried to start with the caboose brakes stuck on. After releasing the caboose, the train still could not start. The problem was that when the train attempted to start with the caboose brake on, it stretched all the inter-car couplings so that the whole train was just like one big car. At this point, the friction from the engine train wheels was not enough to get the whole thing going. Instead, you need to just get one car moving at a time - this is why there is space between the couplings.

I don't understand why it just launches the mutation once and then it throws the error Function called outside component initialization, the only way to make it work is to do something like $: result = mutation(...) but it doesn't make sense, I don't want to run the mutation after each keystroke.

We’re still working on idiomatic Svelte APIs so this one’s also on our list to figure out what the best way forward is

I think Svelte's approach where it replaces component instances with the component markup is vastly superior to Angular and the other frameworks. It gives the developer more control over what the DOM structure looks like at runtime—which means better performance and fewer CSS headaches, and also allows the developer to create very powerful recursive components.

and one which you don’t need to use and won’t add any code to your app if you choose not to use

And of course, if you don't use them you don't pay for them

I was… not one of those assigned to watch our chosen one, so I can’t say much about exactly what happened within the walls of that house, but it seems the fight scarred the place in a way far deeper than simple fire. A scar in reality, that I believe has since been compounded by the interferences of other powers.

Regardless, the effect it had on Agnes was unanticipated. As far as we could tell, she had destroyed the place utterly. And yet she remained bound to it, tied to it in some vital way. I knew when Arthur told me she had kept Raymond Fielding’s hand, that he was worried. But none of us could know what you were going to do.

I was now about to form another being of whose dispositions I was alike ignorant; she might become ten thousand times more malignant than her mate and delight, for its own sake, in murder and wretchedness.

Eliminating needless classes frees up operating memory on the computer—and bandwidth in your head.

I understand what you're getting at, but we shouldn't miss out on useful features just because a few developers will abuse it...

Your styles are scoped to the component. No more leakage, no more unpredictable cascade.

It's fashionable to dislike CSS. There are lots of reasons why that's the case, but it boils down to this: CSS is unpredictable. If you've never had the experience of tweaking a style rule and accidentally breaking some layout that you thought was completely unrelated — usually when you're trying to ship — then you're either new at this or you're a much better programmer than the rest of us.

It gets worse when you're working on a team. No-one dares touch styles authored by someone else, because it's often unclear what they're doing, what markup they apply to, and what disasters will unfold if you remove them. The consequence of all this is the append-only stylesheet. There's no way of knowing which code can safely be removed, so it's common to undo some existing style with another, more specific style — even on relatively small projects.

This giant machine can be your best friend as long as you’re good for the business. But if you accidentally happen to get in its way, it’ll simply screw you over and won’t even notice. If tomorrow a corporate lawyer decides they need to cover their corporate ass more tightly — be it international sanctions, dodging any potential lawsuits from vocal minorities, or anything else — they won’t think twice: they’ll readily dispose of anyone and betray any “ideals” you might have thought they stand for.

many organizations have been burned by the high churn in JavaScript tooling, which sadly moves projects backwards as a part of moving the web forward

A final strand of the development of the prosperity gospel was the development of charismatic Pentecostal churches in America. An umbrella term for a decentralized group of churches — comprising over 700 denominations — Pentecostal churches are characterized by an emphasis on what is known as “spiritual gifts” (or charisms, from which the term “charismatic” is drawn). A worshipful Christian might experience, for example, the gift of healing, or might suddenly start speaking “in tongues.” This tradition of worship meant that, for a believer, the idea that God would manifest Himself to the faithful in concrete, miraculous ways in the here and now was more prevalent than it would be in, say, a mainline Episcopalian church. In addition, the decentralized nature of these churches also meant that individual leaders, many of whom practiced faith healing or similar practices, had a particularly strong effect on their congregations and could build up individual personal followings.

Allows batch updates by silencing notifications while the fn is running. Example: form.batch(() => { form.change('firstName', 'Erik') // listeners not notified form.change('lastName', 'Rasmussen') // listeners not notified }) // NOW all listeners notified

The timescales on which a system’s processes run have critical consequences for its ability to predict and adapt to the future.

We also know that if individuals are bad at collecting good information – if they misinterpret data due to their own biases or are overconfident in their assessments – an aggregation mechanism can compensate.

I don't doubt that we will soon treat the process of logging in as a figurative point of entry, meaning that log into will make full conceptual sense (cf you don't physically delve into a problem or pile into an argument, yet both are correct grammatically because they are semantically [i.e. figuratively])

In graph theory, a tree is a connected acyclic graph; unless stated otherwise, in graph theory trees and graphs are assumed undirected. There is no one-to-one correspondence between such trees and trees as data structure.

There is an observable widespread tendency to give an awk answer to almost everything, but that should not be inferred as a rule to be followed, and if there's (say) a Python answer that involves less programming then surely that is quite on point as an answer for a readership of users.

"When an OP rejects your edit, please do not edit it back in!" Correspondingly, when a user repeatedly does try to edit, understand that something in your framing isn't working right, and you should reconsider it.

In addition to the schema.org structured data format, there are other formats supported by search engines and social media networks. See the supported documentation: Twitter Cards meta tags Facebook Open Graph meta tags

If you can, use AMP like any other JavaScript library to build your site and forget about the canonical linking. Using AMP to build a whole website dramatically reduces your maintenance burden.

The meta charset information must also be the first child of the <head> tag. The reason this tag must be first is to avoid re-interpreting content that was added before the meta charset tag.

A growing number of platforms, vendors, and partners support the AMP Project by providing custom components or offering integration with AMP pages within their platforms.

A growing number of email platforms, clients and providers support AMP for Email within their platforms.

If you have worked with emails before, the idea of placing a script into an email may set off alarm bells in your head! Rest assured, email providers who support AMP emails enforce fierce security checks that only allow vetted AMP scripts to run in their clients. This enables dynamic and interactive features to run directly in the recipients mailboxes with no security vulnerabilities! Read more about the required markup for AMP Emails here.

Because the Web IDE is based on the Monaco Editor, you can find a more complete list of supported languages in the Monaco languages repository. Under the hood, Monaco uses the Monarch library for syntax highlighting.

Introducing Module#const_source_locationUsing Method#source_location made finding the location of any method fairly easy. Unfortunately, there wasn’t an equivalent for constants. This meant that unless the constant you needed to find was defined in your codebase, finding its source location was not easy.

In your environment you may want to always configure internationalization, routers, user data etc. If you have many different React roots it can be a pain to set up configuration nodes all over the place. By creating your own wrapper you can unify that configuration into one place.

Any top-level statement (i.e. not inside a block or a function) can be made reactive by prefixing it with the $: JS label syntax.

According to our understanding of the inconsistencies, the feature was likely trying to support too many edge cases. All caching strategies have weaknesses and eventually break down if the usage is not properly scoped.

If people search through your website, will you guide them to topics first, or will they get a list of individual stories and updates to stories? Does your front page even hint at the fact that people can get more than just the daily news at your site?

For the longest time, whenever I read the news, I’ve often felt the depressing sensation of lacking the background I need to understand the stories that seem truly important. Day after day would bring front pages with headlines trumpeting new developments out of city hall, and day after day I’d fruitlessly comb through the stories for an explanation of their relevance, history or import. Nut grafs seemed to provide only enough information for me to realize the story was out of my depth.
