TypeScript Tutorial #15 - Interfaces

[@Oswee]

You should mention about Interfaces vs Types so that people do not get confused later. :) And in oposite. Mention Interfaces when talking about Type.

[@joaopedroschmitt1112]

I think interfaces intention is not about class structure only, but about creating an abstraction (contract) between two domains that allow you to decouple one part from another by not requiring one part to understand the details of the implementation. A better explanation can be found by searching for the principles of Dependency Inversion, or, Dependency Injection. Interfaces is an essential tool for polymorphism

first thing I do before watching a NetNinja video : hit the like button

[@meylis_so2]

and yours also

[@pulkitaggarwal1931]

Hi, Could you please elaborate difference b/w interface and type for defining any type like isPerson in this video

[@chiubaca]

its confusing... Summary from - medium.com/@martin_hotell/interface-vs-type-alias-in-typescript-2-7-2a8f1777af4c - type aliases can act sort of like interfaces, however, there are 3 important differences ( union types, declaration merging) - use whatever suites you and your team, just be consistent - always use interface for public API's definition when authoring a library or 3rd party ambient type definitions - consider using type for your React Component Props and State

[@helengu]

you can redeclare interfaces multiple times and merge them together.

Thanks Shaun for the wonderful tutorial series.

Hi! bro you are one of my favorite teachers..Stay blessed..

[@rahulyavvari]

Shaun is the best! @1:23 Maybe we have a method speak, cz people speak (lol : ) )

Found naming interfaces a little bit confusing in the tutorial An interface basically describes functionality the object must have so you can interact with it. "Is-something" sounds more how you should name a type guard. I personally prefer just "Person". In the wild, you also may come across a convention to precede interface names with "I" (from "interface"; "IPerson"), like it was popular in Java, for example

[@potantirittisak8494]

Very clear. Thank you!

[@victoradeniji4554]

Thank you so much for this. Thank you.

[@NetNinja]

No worries! :) thanks for watching

[@Pylogicx]

Thanks, a lot. You have saved me time.

[@AnweshAdhikari]

Thanks, this helped!❤

[@NikiL2134]

Why wouldn't I just create a type alias of an object with these properties?

[@mohdkamran530]

Same question

[@andikasaputra1390]

So, what is the difference between type & interface?

[@samuelopeyemi8377]

Type is what typescript infered or inbuilt type you declear e.g number, string. While interface is your custom type that doesn't come with TypeScript

[@itaibiton9068]

@@samuelopeyemi8377 yea but you can also create types

[@usama_khalid]

your videos are great. i have a request - please make videos on Nuxt js (Vue ssr)

[@cyanfroste5559]

interfaces are mostly used with classes to define a class, but in js, classes are just glorified objects. so the differences are very small.

[@gaddiji]

can you explain me Interfaces, i cant understand wth is this..

[@mylesdavies9476]

It's odd that you can't extend the object with additional properties. Surely as long as it still satisfies the interface, additional properties shouldn't be a problem. This would be allowed in C# for example and would be very common, for example an object implementing multiple interfaces through a range of different properties and methods.

[@matheuscampos2566]

great... tnx

[@crucru4000]

Which syntax highlighter do you have enabled here? very cool

[@avtheprowd]

Did you find it ?

[@nomads_._land]

@@avtheprowd That was me 2 years ago haha. No, but I use synthwave80 on vscode for everything except solidity :)

[@avtheprowd]

@@nomads_._land On which domain are you working on this days ?

[@Santix_Oficial]

I have an Issue at compile time Uncaught ReferenceError: exports is not defined at my app.js file on the line Object.defineProperty(exports, "__esModule", { value: true }); someone help me please.

[@loba8924]

Thanks

[@bouamarelouahhabi9525]

I hope after this series you do another one about mern or mevn stack with typescript (a big one, it could be in udemy), you're the best man!

[@avigarg3357]

how can we use pick utility type on new someone person you made from same interface"inperson"

[@priyojitsingha]

So interfaces can be considered as schemas for a object, am I right?

[@AP-no6uc]

Hello! Can you tell me please which color theme you use in VS Code? it looks nice.

[@TheMisieq93]

I think he uses Monokai++

[@R_Samnan]

Super cool

[@johnconnor9787]

What is the difference between Interface and Type aliases?

[@Djinn667]

This is similar to classes in C++

[@zes7215]

wrg, sx any nmw and any s perfx, not stringx etc

[@Mikevets]

How is Interface different from Type Alias?

[@ridl27]

ty.

[@amanin4326]

whatsup with the 30 man ?

[@vaibhavshukl8265]

Can you make one series on Wordpress and one on Native android development using Kotlin?

[@aayushkumarthakur3095]

Make a method speak because people do speak 🙂

[@imdeadserious6102]

When you're taught that JS has nothing to do with Java, then JS becomes Typescript and as close to Java as it can be... I really don't like typescript... but full stack school. yay

[@ademineshat]

Are you really 30? 😂
