Object Oriented vs Functional Programming with TypeScript 

If anyone interested i found this interesting video about Object Oriented Programming and why it's bad -> ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QM1iUe6IofM.html

Actually the guy who created GIF says it's pronounced "JIF" and the sound comes from GEE the letter, not what it stands for, Graphics. This will be a never-ending argument... to-may-to, to-mah-to.. :)

dude do you really have to use so many emojis ? are you gen z?

@@nikhilshankar4190 why do you have a problem? We are gen Z and we love it. If it wasn't for the emojis then I might not have subscribed.

Save me, Superclass! I will, though I don't have a method to handle lasers. _Gets vaporized by a laser._

@@TheVanuPhantom 😂

Not really

A SuperHuman is basically a Human who finished his studies 🤣😂

It makes sense if you think of clasess as sets.

Or too fast so that you'll need to set the speed to 0.75.

It is not about 'speaking fast' it is all about 'already prepared pieces of code' which create such an effect

I still have him at 1.5x

1.25x?? 2x and waiting for RU-vid to let me go faster!

@@prajjwalsharma. OOP for wrappers, FP for everything else. If your functions have the same prefix, it might be a good idea to make them methods on object instead

In the compositional world, it does not matter whether a hotdog is a sandwich. You can hold it and eat it like a sandwich, and that is good enough :)

better : the way it gets the job done

You use both. Inside you classes you write methods that does procedural stuff.

@@Limpuls What are you referring to is "imperitive" programming. OOP and procedural programming are not the same. They both are imperitive (mostly), but no, they're not the same. Just because you're writing functions doesn't mean it's a procedural or functional programming. There are certain traits specific to functional (like pure functions only, very declarative approach etc) and to the procedural (modules, procedures/functions, side-effects allowed, structure is purely imperitive). Each of us in our day to day work uses some parts of imperitive and functional programming to some degree and very few of us actually doing pure functional (Haskell etc) or pure procedural (well, pure procedural is nearly non-existent nowadays... like COBOL for example). The most commonly used nowadays is OOP imperitive programming with some functional programming on top of it to make life easier. Pure functional is VERY hard to do properly, believe me...

Procedures have side effects functions do not

functional programming is not procedural programming

lul, widzialem cie tez pod romanem

Or is it a well-inherited video... hmmm?

It's quite functional too, objectively speaking.

@@misterrodger I extend your opinion

This thread is in a class of its own

i had a stroke reading your comment

I had a stroke reading this too

had a stroke too

@@fenrir5211 Was wondering if that was me or his comment LOL

Thank you Kevin. Ready for a much needed break, but have some cool stuff in the works for 2019.

I agree 100% - the bigger point was that this stuff is not religious dogma. Basically every js project I've been involved in uses some combination of these paradigms.

@@Fireship Exactly. As for the other questions: I use pronunciation gif, and a hotdog is a taco.

I think OO pretty much solidified the backend and functional the front

That's exactly what this video said. But thanks for the summary I guess

just saying, if the video is accurate on day 1 why would it be less accurate after 3 years

Same, only discovered now and it's jaw dropping to me

1. yes. 2. its edited not auto filling

i concur

Are you there??

yeah, how did it went?

It's called Quokka.js

@@SiddiqNx Thanks so much buddy!

@@SiddiqNx Thanks!

WallabyJS, from the same guys, also blew my mind: wallabyjs.com, it "runs your JavaScript and TypeScript tests immediately as you type, highlighting results in your IDE right next to your code."

And for emoji it's plugin named Emoji, it's not useful but it's kinda fun

k

Console.log ?

Looks like quokkajs.com/ to me :) I'm also using that frequently to test stuff out

@@felixrichnau Console.log ?

same question, it doesn't show in the editor like the video

Por qué no aprende usted inglés? Le puede ayudar a usted mucho. O chineso tal vez sería más útil.

You've found it yet? thanks

The Stategy Pattern is just a function. The only reason it exists is because OO languages like Java didn't have first-class functions back in the day. It's not necessary in JS.

Probably quokka

Junhai Yang traits are just glorified copy-paste in PHP - nothing more. Composition is something different, to be honest that this video failed to explain,.

does deep copy via lodash methods add less computational overhead. And does it count as antipattern or bad practice to mutate state values ?

items.map(elem => ({...elem})). Don't know about the performance though

That's good, I was worried people would not get my dry sense of humor

Check out the live stream in the video feed from a few months ago where I give away all these secrets

search on vs code themes, you will find lots of it.

Fira Code

I think this is Quokka.js

@@KamenMinkov Thanks Kamen =)

He answered before ;) quokkajs.com/docs/index.html

Quokka

fira code

yes, but it would consume a lot of time. Can open your editor along with video to have hands on.

Thank you commenter from the past, that's what I was thinking but couldn't put into words.

agree

Theres also wallaby which is less playground (snippet) based. Same creator I think.

Oh I just thought he did type it or copy paste it manually.. 😅 Awesome plugin!

Check languages like Haskell. There is a lot of composition, and the types are brilliant. Typescript really just isn't that good of a system
