Ephemeral is just a fancy word for non-persisting. Something can be ephemeral and immutable tho. Anything in-between is called partially persisting. Also memoization is caching the result value of (pure) functions for some specific inputs, e.g. the cache key are the input parameters.

@perrym8048

I find the ephemeral being defined as the opposite of immutable not really true. Immutable doesn't mean persisted, it just means it can't be changed. Ephemeral would simply be something that doesn't last for a very long time (or doesn't persist). I've never heard a javascript object be defined as ephemeral. In that case, anything in the call stack is ephemeral (which is true, but not particularly helpful to think about it that way).

One oversimplified example for ephemeral + immutable: On application startup you check if the OS is Linux and set a readonly global boolean "IsLinux".

I'm not sure if that's a really good explanation in terms of typescript, I always thought that abstract classes should only contain methods that are not yet implemented, so they have to be overloaded in derived classes.

@@gamerzero6085 There are multiple ways of looking at it. Both make sense. For one, an abstract class can be a base class of two different classes, which doesn't make sense to instantiate on its own. The other, as you said, is an abstract class, for which not all implementation details are known yet. Often, both occur simultaneously.

I would think of abstract classes as making it not instantiate on its own Because it doesn't have all the implementation details, I feel like those go hand in hand, at least I can't imagine a scenario where that's not the case. and if it was only abstract methods I might just vouch for an interface.

I'm big about terminology in programming, especially when tutoring. I try to emphasize to my students that using the right words makes communication much more efficient and finding the correct terms deepens your understanding of the subject. However, I'm also a bit of an etymology nerd so I may go too far with it sometimes... most of the time...

@@devstuff2576 I agree that a good communicator need to be able to describe concepts in terms that are close to the target audience. However, I still believe that having good vocabulary and being able to compactly and precisely express ideas using "industry standard" terms in a professional setting among peers is advantageous. Also I don't think that building such vocabulary is a matter of memorization, but rather of exposure to the subject matter. E.g. I wouldn't require a student to know the difference between terms "anonymous function" and "arrow function" in Javascript right after they're introduced to the concepts, but rather after they're comfortable with it, but I would always make sure to use the terms correctly myself and gently correct any misuse of terminology.

Thank you! The more time I spend in the programming world, the more I wish we could all just have a glossary in front of us and completely agree on the meaning of words like these.

I loved the way you presented and introduced each term. Very useful for me as a software developer and I'll definitely be sharing it with friends who need it. Please make more like this!

Awesome video with great details. I wish all of your videos/ tutorials would be detailed/indepth like this one. You'd be the best instructor out there imo.

Amazing content, remember it took me years to learn these terms by picking the up over time. This is a great and accurate summary!

I recognize idempotent from my discrete math class. The idempotent law, which is basically saying if there a prepositional statement p (boolean) then p OR p is equivalent to p. P AND p is equivalent to p

Thank you for this video, Jeff! There was definitely a word or two (like idempotent and ephemeral) that I've heard before but didn't really understand.

This was one of the most useful videos ever i have added it to my significant playlist

From Wikipedia: The term "memoization" was coined by Donald Michie in 1968 and is derived from the Latin word "memorandum" ("to be remembered"), usually truncated as "memo" in American English, and thus carries the meaning of "turning [the results of] a function into something to be remembered".

My brain! Watched each segment twice to ensure I fully understood. Thank you for the great videos!

Brilliant! I like you explaining the etymology of these terms.

I loved the intro and outro lol I always tell folks when getting into coding the first hard part is learning the terms.

Please do more of these! Loved it

Great vídeo! Thanks for that. Anxious for the sequel! :)

I would say that it's more accurate that while learning software engineering you have to learn some new concepts. These new concepts have words we are unfamiliar with, so for some reason we attribute them as "fancy". Many of the concepts are intuitive though, so it's just a matter of learning the vernacular.

Serialisation need not necessarily involve conversion to a language independent format (of which JSON would be an example) for interop. It can also mean dumping object state to file, within a language itself for resumability or streaming.

I prefer to think of idempotency as only having an effect once. Pressing the crosswalk button multiple times has the same effect as pressing it once, but that first press has a different effect than not pressing it at all.

@pharoah327

Жыл бұрын

I agree. Saying it has the same effect can be misleading. It has the same power but not same effect. For example the absolute value function. The first time it is used can have a different effect than using it again and again on the same value. But all times after the first will result in the same value returned. Essentially the power is in the first time it is used.

@SophieExMachina

@@ArchonLicht Yeah this video isn't as great as people think lol His definition of abstraction is also not perfect. He described inheritance, not abstraction. Abstraction is for example if you have a data structure with a .sort() method. You just call .sort() on it and you expect a certain outcome (a sorted collection), and you don't care how it sorts itself. Meanwhile the data structure can have a way it gets its output (for example quicksort or something), but then the developer of the library decides to switch out the sort for a faster sorting implementation. You keep using .sort() on it and it keeps giving the same result of a sorted collection, but it does it entirely differently than before and you don't even notice. This is abstraction. Creating an API (API as a term can be used for web APIs but also code libraries) where you hide useless implementation details but give out what the function takes and what it will output. This should always remain consistent but the implementation can then be done in a million different ways and the consumer (user of the API) never has to care or know.

Can you make a video on all the customisation you have made on VSCode. Your vs looks great!!!

Very ephemeral. Good to see your idempotence.

How do you make the code pop up chunk by chunk in VS Code? Is there some trick or extension to it or is it just working with ctrl + z? Love your videos btw!

I was expecting more!

I've never heard someone say "idem-po-tent" before. In the UK this is pronounced "i-dempotent" - where the "o" in potent is not emphasised.

Thanks for sharing this content. A few remarks, though: A good example of predicates is the function you pass as the argument of the filter function on arrays. Your example with isCat, however, is a misunderstanding of OO and polymorphism. Both Cat and Dog should have a function makeSound() and their implementing classes then yield the respective result. No if needed. Your example means that for each additional animal you need to add 1 more is... function and you need to add it to the union type and you need one more if block in makeSound. This violates the Open Closed Principle and it is measurably more complex (check the CCN). Secondly, you are right that abstraction means to hide implementation details. Declaring a class "abstract" is not the answer here. Many abstractions exist without OO concepts like inheritence. Your code achieves DRY but not abstraction per se.

at 4:44 I might be wrong but I think TS is not strongly typed because you can coerce values into other types because ultimately it is JS. It does have optional static typing.
