You should take care, however, to make sure that your individual objects can stand alone as much as possible. Tightly coupled objects are objects that rely so heavily on each other that removing or changing one will mean that you have to completely change another one - a real bummer.

Anything that isn't explicitly enforced by contract is vulnerable to misunderstandings. It's doing your teammates a great service, and reducing everyone's effort, by eliminating ambiguity and enforcing information flow by design.

Web sites often design their APIs to optimize performance forcommon cases. Their main object-reading methods may return onlycertain “basic” properties of objects, with other methods availablefor fetching other properties. ShapirJS hides this performanceoptimization complexity from the user.

Considerations

In Lua you can write raw, multiline strings with [[]]: [[ Alice said "Bob said 'hi'". ]]

how important is the concrete syntax of their language in contrast to

there is no single perfect universal programming language. Until I came to that point, I wasted a lot of time thinking that GW-BASIC QBASIC QB 4.5 VB4 Delphi Java C++ C# 1.0 was the only language I would ever need

The LISP part, though, is not going well. Porting clever 1970s Stanford AI Lab macros written on the original SAIL machine to modern Common LISP is hard. Anybody with a knowledge of MACLISP want to help?

I find C++ quite ugly

There are no static variables and no initialization

The fundamental mistake of Node.js was diverging from the browser

an acknowledgement of network effects: LP is unlikely to ever catch on enough to be the majority, so there needs to be a way for a random programmer using their preferred IDE/editor to edit a "literate" program

memory usage and (lack of) parallelism are concerns

local a (e.g. aPoint) param p (e.g. pPoint) member instance m (e.g. mPoint) static s (e.g. sPoint)

This can get much worse than the above example; the number of \’s required is exponential in the nesting depth. Rc fixes this by making the backquote a unary operator whose argument is a command, like this: size=‘{wc -l ‘{ls -t|sed 1q}}

comparing the event and window.event isn't enough to know if event is a variable in scope in the function or if it's being looked up in the window object

In 1994, The Unix-Haters Handbook was published containing a long list of missives about the software—everything from overly-cryptic command names that were optimized for Teletype machines, to irreversible file deletion, to unintuitive programs with far too many options. Over twenty years later, an overwhelming majority of these complaints are still valid even across the dozens of modern derivatives. Unix had become so widely used that changing its behavior would have challenging implications. For better

Object hierarchies are very different from relational hierarchies. Relational hierarchies focus on data and its relationships, whereas objects manage not only data, but also their identity and the behavior centered around that data.

Understanding a strange codebase is hard.

We would prefer: stay within single host language, but make code lookas declarative as possible.

Introduce behaviour that is likely to surprise users. Instead have due consideration for patterns adopted by other commonly-used languages.

Each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful, and versatile.

provide interfaces so you don’t have to think about them

In programming language design, a first-class citizen (also type, object, entity, or value) in a given programming language is an entity which supports all the operations generally available to other entities. These operations typically include being passed as an argument, returned from a function, modified, and assigned to a variable.

In object-oriented programming, information hiding (by way of nesting of types) reduces software development risk by shifting the code's dependency on an uncertain implementation (design decision) onto a well-defined interface. Clients of the interface perform operations purely through it so if the implementation changes, the clients do not have to change.

Programming to interfaces is at the core of flexible structure.

The more important point comes from a program design perspective. Here, "programming to an interface" means focusing your design on what the code is doing, not how it does it. This is a vital distinction that pushes your design towards correctness and flexibility.

The $ contract for auto-sub­scrib­ing is lovely in its sim­plic­ity and flex­i­bil­ity. You can adapt your own preferred state-man­age­ment pattern or library, with or without Svelte stores as helpers. Svelte does not fuss about how you want to manage your state.

detach, as an api, should be declarative (ensure the node is detached) instead of imperative (detach the node), allowing it to be called multiple times by performing a noop if the node is already detached. This way, it won't matter if the node is removed from the DOM from outside of svelte.

For my point of view, and I've been annoyingly consistent in this for as long as people have been asking for this feature or something like it, style encapsulation is one of the core principles of Svelte's component model and this feature fundamentally breaks that. It would be too easy for people to use this feature and it would definitely get abused removing the style safety that Svelte previously provided.

we need to step back and make a closer look at the DRY principle. As I mentioned earlier, it stands for "Don’t Repeat Yourself" and requires that any piece of domain knowledge has a single representation in your code base. The words domain knowledge are key here. DRY is not about duplicating code. It is specifically about duplicating domain knowledge

Don’t go to code academy, go to design academy. Be advocates of the user & consumer. It’s not about learning how to code, it’s about translating real-world needs to technological specifications in just ways that give end users agency and equity in design, development and delivery. Be a champion of user-centric design. Learn how to steward data and offer your help.

for example, comments and identifiers

If one object is part of another object, then we use a diamond at the start of the arrow (next to the containing object), and a normal arrow at the end.

One thing Component taught me was to think of the entire system like an Object. Specifically, there is state that needs to be managed. So I suggest you think about -main as initializing your system state. Your system needs an http client, so initialize it before you do anything else

Rob Pike has described Plan 9 as "an argument" for simplicity and clarity, while others have described it as "UNIX, only moreso."

Do you need to learn code to use The Grid? No coding is required to use The Grid. Just do what you're already doing on Facebook, Twitter, Instagram, etc. Post images, video, and content to your site and our AI Designer will make it beautiful. If you know code, you can extend functionality using our platform tools and API.

Once you abandon entirely the crazy idea that the type of a value has anything whatsoever to do with the storage, it becomes much easier to reason about it. Of course, my point above stands: you don't need to reason about it unless you are writing unsafe code or doing some sort of heavy interoperating with unmanaged code. Let the compiler and the runtime manage the lifetime of your storage locations; that's what its good at.
