    1. TypeScript is an extension of JavaScript. You can think of it as JavaScript with a few extra features. These features are largely focused on defining the type and shape of JavaScript objects. It requires that you be declarative about the code you're writing and have an understanding of the values your functions, variables, and objects are expecting.While it requires more code, TypeScript is a fantastic means of catching common JavaScript bugs while in development. And for just that reason, it's worth the extra characters.
    1. Webpack's resolve.mainFields option determines which fields in package.json are used to resolve identifiers. If you're using Svelte components installed from npm, you should specify this option so that your app can use the original component source code, rather than consuming the already-compiled version (which is less efficient).
    1. According to Netflix, the Netflix app asks this question to prevent users from wasting bandwidth by keeping a show playing that they’re not watching. This is especially true if you’re watching Netflix on your phone through mobile data. Every megabyte is valuable, considering that network providers impose strict data limits and may charge exorbitant rates for data used on top of your phone plan. Advertisement tmntag.cmd.push(function(){tmntag.adTag('purch_Y_C_0_1', false);}); Of course, this saves Netflix bandwidth, too—if you fall asleep or just leave the room while watching Netflix, it will automatically stop playing rather than streaming until you stop it. Netflix also says this helps ensure you don’t lose your position in a series when you resume it. If you fall asleep in the middle of your binging session, you might wake up to find that several hours of episodes have played since you stopped watching. It will be difficult for you to remember when you left off.

    1. As for why - a GET can be cached and in a browser, refreshed. Over and over and over. This means that if you make the same GET again, you will insert into your database again. Consider what this may mean if the GET becomes a link and it gets crawled by a search engine. You will have your database full of duplicate data.

    1. We should test for events emitted in response to an action in our component. This is used to verify the correct events are being fired with the correct arguments.

    1. The reason Final Form does this is so that pristine will be true if you start with an uninitialized form field (i.e. value === undefined), type into it (pristine is now false), and then empty the form field. In this case, pristine should return to true, but the value that the HTML DOM gives for that input is ''. If Final Form did not treat '' and undefined as the same, any field that was ever typed in would forever be dirty, no matter what the user did.
    1. So why the over-complication? What we got now is replicating a chain of && in the former version. This time, however, you will know which condition failed and what went in by using tracing. Look at the trace above - it’s impossible to not understand what was going on.

    1. Why the ^=? This means "starts with", because we can also have variation placements like top-start.
    1. Why is CORS important? Currently, client-side scripts (e.g., JavaScript) are prevented from accessing much of the Web of Linked Data due to "same origin" restrictions implemented in all major Web browsers. While enabling such access is important for all data, it is especially important for Linked Open Data and related services; without this, our data simply is not open to all clients. If you have public data which doesn't use require cookie or session based authentication to see, then please consider opening it up for universal JavaScript/browser access. For CORS access to anything other than simple, non auth protected resources
    1. The same-origin policy fights one of the most common cyber attacks out there: cross-site request forgery. In this maneuver, a malicious website attempts to take advantage of the browser’s cookie storage system.
    1. Why? I wrote MagpieRSS out of a frustration with the limitations of existing solutions. In particular many of the existing PHP solutions seemed to: use a parser based on regular expressions, making for an inherently fragile solution only support early versions of RSS discard all the interesting information besides item title, description, and link. not build proper separation between parsing the RSS and displaying it.

    1. Why Vala? Many developers want to write GNOME applications and libraries in high-level programming languages but can't or don't want to use C# or Java for various reasons, so they are stuck with C without syntax support for the GObject type system. The Vala compiler allows developers to write complex object-oriented code rapidly while maintaining a standard C API and ABI and keeping the memory requirements low.
    1. These are valid comments. I think it is worth noting that svelte didn’t choose a non-javascript method for fun or because we think we should redesign the language. The additional constructs, for the most part, are there to allow svelte to more clearly work out exactly what is going on in the code in order to optimise. In short svelte needs a certain amount of information to do what it does and pure javascript is often difficult to analyse in this way. But I appreciate your concerns and comments and we try to take all feedback on board where we can. So thank you!

    1. I really dont need a solution to this problem! I can find many workararounds

      Actually, the answer that was given was a good answer, as it pointed to the problem: It was a reminder that you need to:

      assign to a locally declared variable.

      So I'm not sure the answer was intended to "just" be a solution/workaround, but to help correct or fill in the misunderstanding / forgotten piece of the puzzle to help OP realize why it wasn't working, and realize how reactivity is designed to work (based on assignments).

      It was a very simplified answer, but it was meant to point in the right direction.

      Indeed, it pointed to this main point that was explained in more detail by @rixo later:

      Personally, this also totally aligns with my expectations because in your function fruit can come from anywhere and be anything:

    1. Why do we use bundlers again?Historically, bundlers have been used in order to support CommonJS files in the browser, by concatenating them all into a single file. Bundlers detected usages of require() and module.exports and wrap them all with a lightweight CommonJS runtime. Other benefits were allowing you to serve your app as a single file, rather than having the user download several scripts which can be more time consuming.

    1. Then when giving answers I'm even less certain. For example I see occasional how-to questions which (IMO) are ridiculously complex in bash, awk, sed, etc. but trivial in python, (<10 lines, no non-standard libraries). On such questions I wait and see if other answers are forthcoming. But if they get no answers, I'm not sure if I should give my 10 lines of python or not.
    2. 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.

    1. A well-formatted and descriptive commit message is very helpful to others for understanding why the change was made, so please take the time to write it.

    1. This task disables two-factor authentication (2FA) for all users that have it enabled. This can be useful if GitLab’s config/secrets.yml file has been lost and users are unable to log in, for example.
    1. I appreciate the vigilance, but it would be even better to actually publish a technical reasoning for why do you folks believe Firefox is above the device owner, and the root user, and why there should be no possibility through any means and configuration protections to enable users to run their own code in the release version of Firefox.

    1. I believe that mere lists of "vote yes" or "vote no" are not very helpful except for sheep: it's important to know why one is urged to vote in any given direction.

    1. Let's make the example even easier. function convertDate<T extends string | undefined>(isoDate?: string): T { return undefined } 'undefined' is assignable to the constraint of type 'T' Means: What you return in the function (undefined), matches the constraints of your generic type parameter T (extends string | undefined). , but 'T' could be instantiated with a different subtype of constraint 'string | undefined'. Means: TypeScript does not consider that as safe. What if you defined your function like this at compile time: // expects string return type according to generics // but you return undefined in function body const res = convertDate<string>("2019-08-16T16:48:33Z") Then according to your signature, you expect the return type to be string. But at runtime that is not the case! This discrepancy that T can be instantiated with a different subtype (here string) than you return in the function (undefined) is expressed with the TypeScript error.

    1. the proposition that diverse motivations animate human beings, and, more importantly, that there exist ranges of human experience in which the presence of monetary rewards is inversely related to the presence of other, social-psychological rewards.

      The first analytic move.

    2. understanding that when a project of any size is broken up into little pieces, each of which can be performed by an individual in a short amount of time, the motivation to get any given individual to contribute need only be very small.

      The second analytic move.
