Trivial doesn't mean it wasn't well thought out. On the contrary the more trivial the abstraction the more likely its more general, since it has less constraints.

Depends on what you mean by "good abstraction". If I wish to use sum types to represent discriminated unions and parametric polymorphic types then yes its better to make sure the type "sets" don't intersect. I would

by spion 9y ago
This doesn't sound right Sum types are not more capable of an abstraction than union types. If we consider them in isolation, they are strictly less capable. For example, its possible to model sum types using union types in TypeScrip

Try TypeScript or ReasonML or ScalaJS. They all compile to JS and have dead-easy FFI so you can still use the ecosystem stuff you're used to, but you learn something new. In the case of ReasonML and Scala you get to use them later with

Should've clarified that "first class support" wasn't really about the VM but mostly about the library ecosystem.

re: Clojure, the stack traces I think explain the issue (they're pretty terrible, you can see the Java guts). With Scala its probably better, but still the impedance mismatch shows here and there (the Java ecosystem doesn't use ca

Its so funny, watching Java fans talking about silly things like `var` whilst their language gets more obsolete every day. I'm so sorry, but basic type inference won. Can you please go away so we can get a good ecosystem and a good l

You need escaping only when you're sending strings to a compiler (which is what you do when you do server-side rendering), and its a never ending source of bugs. You basically need to re-implement the entire logic of a full blown parse

You're getting downvoted because you're equating Angular 1, React and Vue. React has one huge difference: its "template language" is (almost) never compiled at run time. Its not HTML at all. This makes it difficult to co

The surface problem of LISP are the parenthesis. The deeper problem is that its a very potent NIH enabler: most of us are not really that talented or have the time to properly invent things; those that are tend to not quite like other peopl

What about tarball extraction and native module build artefacts being produced? They'll still have the wrong permissions. This was not originally about "mkdirp". It was about managing the cache when running with sudo on ubunt

You want to know how this happened? It all started with ubuntu pointing home to the user's dir when running sudo. This was done out of convenience to have gedit and other Xorg apps work when run with sudo... Then there is also the terr

No structural comparison: MobX will stop dependant recomputation if the new value of an intermediate recomputation is equal to the previous value. You also have the option of using structural equality instead of reference equality (and also

The number of tricky corner cases in MobX are very few. Also, once the implementation switches to proxies the vast majority will disappear. I'm willing to accept a few corner cases as long as there is a large common subset of functiona

I don't want to use surplus because e.g. I want to use well developed UI components or toolkits like blueprintjs, which is implemented on top of React. Slightly confusing is a real objection. MobX strives to implement transparent react

by spion 9y ago
Slightly confusing api, no structural comparison, no adapters for popular frameworks (e.g. S.js-react or S.js-preact), no laziness (computations are recomputed even if they're not requested by reactions).

I elaborated that case in the most detail, but there are many other problems that generators solve mentioned in the blog post. Another very common one is getting the current user that initiated the request (or maybe their session), which yo

MobX is the most powerful front end development library on the market right now. It single-handedly solves the cache invalidation problem in a performant way, and its pluggable into any framework. And yes, promises limit it.

This has nothing to do with it. I love promises but they are truly limiting. Here is an example of how promises limit the power of mobx https://twitter.com/spion/status/958906847385341952 Another example relevant

People hate having a build step and will go to great lengths to get rid of it. To add on top of that, the situation with writing modular code in JavaScript/HTML/CSS is such a total disaster - even with a build step. Of course, the

Thats a little presumptuous. We're doing the best we can to build complex applications, on top of a platform that still has no proper module system, no UI toolkit except a wonky document model on top of which bloatedness was built, san
