To understand this helper, you should understand that every step invocation calls Output() for you behind the scenes. The following DSL use is identical to the one [above]. class Execute < Trailblazer::Activity::Railway step :find_provider, Output(Trailblazer::Activity::Left, :failure) => Track(:failure), Output(Trailblazer::Activity::Right, :success) => Track(:success)
-
Please note that the I/O DSL is only providing the most-used requirements. Feel free to use the low-level taskWrap API to build your own variable mapping with different scoping techniques.

It's hard to say why people think so because you certainly don't need to know category theory for using them, just like you don't need it for, say, using functions.

The assert method is used by all the other assertions. It pushes the second parameter to the list of errors if the first parameter evaluates to false or nil.
Seems like these helper functions could be just as easily used in ActiveRecord models. Therefore, they should be in a separate gem, or at least module, that can be used in both these objects and ActiveRecord objects.

While custom iterators are a useful tool, their creation requires careful programming due to the need to explicitly maintain their internal state. Generator functions provide a powerful alternative: they allow you to define an iterative algorithm by writing a single function whose execution is not continuous. Generator functions are written using the function* syntax.

Can I use the title attribute?Yes. The content prop can be a function that receives the reference element as an argument and returns a string or element.tippy('button', { content(reference) { const title = reference.getAttribute('title'); reference.removeAttribute('title'); return title; }, });The title attribute should be removed once you have its content so the browser's default tooltip isn't displayed along with the tippy.

For both the tailor-customer and doctor-patient examples, personal data is an input used to improve an output (dress, suit, medical treatment) such that the improvement directly serves the interests of the person whose information is being used.
This reminds me of "Products are functions" where your personal data is a variable than enters into the function to determine the output.

Doing so also means adding empty import statements to guarantee correct order of evaluation of modules (in ES modules, evaluation order is determined statically by the order of import declarations, whereas in CommonJS – and environments that simulate CommonJS by shipping a module loader, i.e. Browserify and Webpack – evaluation order is determined at runtime by the order in which require statements are encountered).
Here: dynamic loading (libraries/functions) meaning: at run time

All validators can be used independently. Inspried by functional programming paradigm, all built in validators are just functions.
I'm glad you can use it independently like:
FormValidation.validators.creditCard().validate({
because sometimes you don't have a formElement available like in their "main" (?) API examples:

This isn't really a bug, because if you have an async function that returns a function, it doesn't really return a function - it returns a promise. I don't remember whether the Svelte internals currently check for the onMount callback's return being a function or whether they check for it being truthy. Maybe there's some adjustment to be made there.

Functions have lots of interesting and useful properties. You can isolate them. You can compose them. You can memoize them. In other words, functional UI feels correct, and powerful, in a way that wasn’t true of whatever came before it. I think this is why people get quasi-religious about React. It’s not that it’s Just JavaScript. It’s that it’s Just Functions. It’s profound.

You should construct evergreen (permanent) notes based on concepts, not related to a source (e.g. a book) or an author.
Your mental models are compression functions. You make them more powerful by trying to use them on new information. Are you able to compress the new information with an already acquired function? Yes, then you've discovered an analogous concept across two different sources. Sort of? Then maybe there's an important difference, or maybe it's a clue that your compression function needs updating. And finally, no? Then perhaps this is an indication that you need to construct a new mental model – a new compression function.

Since TypeScript 1.4 static extensions can be added easily. The TypeScript team changed the lib.d.ts file to use interfaces for all static type definitions. The static type definitions are all named like [Type]Constructor: So if you want to add a static function to type Object, then add your definition to ObjectConstructor.

To return data after an asynchronous operation, return a promise.
I just struggled for a few hours trying to resolve some errors about CORS and 500 INTERNAL errors.
This line is a bit misleading.
In trying to get things up and running, I was returning a simple JSON object rather than a Promise. According to what I found, even if you don't have any async work, you still need to return a Promise from your function.

More details on the Green function theory may be found in standard text books on many-bodytheory (e.g. Nozi`eres 1964, Fetter and Walecka 1971, Inkson 1984, Mahan 1990) and in the reviewarticle by Hedin and Lundqvist (1969).
Really important references, esp the Fetter and Walecka many body quantum book.
