Advanced Golang: Channels, Context and Interfaces Explained

Today, I'll provide a simple breakdown of channels, context and interfaces in Golang. I'll show examples of why they are useful and how to properly use them in the real world.
0:00 Intro
0:17 Channels
8:35 Context
13:55 Interfaces
21:53 Conclusion
Channels are a safe way of transferring data between goroutines without using a mutex. You can send data to a channel in one goroutine, then consume data from the same channel in another goroutine. By default, a channel does not have space to store data, so you must simultaneously send and receive data from the channel to avoid a deadlock. A buffered channel allows you to allocate space to temporarily store data in the channel.
Context is an object that can be safely passed to multiple goroutines to provide a way to implement a timeout or cancellation to a function. 3rd party libraries that make HTTP requests or database requests typically have support for providing your own context so you cancel those operations.
Interfaces are a great way to enforce a blueprint for what your app can do, similar to object oriented programming. For example, there are many different types of bank accounts, but you can use a single interface to interact with all of them: GetBalance(), Deposit() and Withdraw(). This makes your high-level code easier to work with because the implementation is abstracted away.

this guy just chilling on his bed while explaining complex staff, loving it haha

[@robimalco]

Ryan you probably are already aware of it, but you have such a talent in explaining stuff. Thanks for your work. Keep exploring Golang please

[@TechEats]

waiting eagerly for more

[@shmeleff_ural]

Agreed

[@gregsullivan7408]

It also helps that he speaks fluent English, with a great voice

[@abeldelapaz2153]

Love it, talking about advanced software concepts while chilling on his bed. Legend 👏

[@thor_]

The best way of working!

[@esra_erimez]

Your voice is ASMR but the best part is you know what you're talking about and how to explain it.

[@David-xy4nw]

This video is a gem, It would have been awesome if you could have a series for advanced golang. I am sure other viewers would want that too !

[@jamestk656]

I've read several books on Go but your explanations have been clearer and more concise to me. I especially like your description of (unbuffered) channels as being portals that don't store anything and why they could result in a deadlock. I never really understood that from my readings until you explained it.

[@vanjastojanovic5023]

Amazing video series for go, I love hearing advanced topics in a new language, that I can carry over from previous ones I know.🎉❤

[@exxzxxe]

Ryan- you have a natural ability for simply explaining complex topics. Good job!

[@ngjimmy]

I love your isolation method of explaining code

[@DJStompZone]

My guy really recorded a whole KZbin video from bed, that's gotta take a lot of moxie. Every other video on this channel I've watched has been super clean and professional though, so I'll allow it... This time 🤣

[@taqitahmid50]

Your voice is almost ASMR level! Also, great explanations.

[@pp09997444828]

couldn't understand it better .. you are champ.. thanks Ryan :)

[@erichshan7964]

your casual style makes information so much more accessible. i subbed!

[@senthilramalingam9500]

Dude, your explanation is crystal clear, very specifics and more importantly no blabbering. You should put more tutorials or create a course in udemy man...

[@johnnychang3456]

Hey Ryan this is great quality content! Please do more Go videos as there’s not much on KZbin. Keep up with the good work!

[@rshraddha]

Great tutorial Ryan. Finally I can actually understand contexts in Go.

[@salvaje1]

Damn, I like how this guy explains things. He oozes experience just from how he talks, and doesn't look like he's reading from an off screen document. Like he was working on some go code and thought it would be nice to share it in a video. He also doesn't just regurgitate what is in the docs like others.

[@stevekamga5977]

Hey Ryan, you have a talent. Thank you for your videos

[@MelodyLu9000]

Your explanations and demos here are the best! Really helped me get the concept. Thank you so much for making this video!

[@ireenisabel988]

Man, you have a voice of morgan freeman and a potential to be a great teacher like Feynman.

[@vl.v]

Lovely explanations, I'd love to see more of you, very well spoken and presented!

[@jondoe79]

We need more of golang, your content is superb and easy to understand, very practical examples.

[@amesasw]

Man, excellent video. Nice to see someone put together solid examples and walk through them well.

[@SanaagSomaliland]

You explained these very well. Thanks.

[@VadimCebotari]

Love how you explain the concepts. Keeping them simply and clear. Thanks a lot for the great work

[@bruceleeharrison9284]

I hadn't touched Go in a couple years, and this video was a perfect refresher to jog my memory on the operation of channels. Nice job!

[@ramgopal2520]

I have gone through the basics of Golang. I had trouble understanding interfaces and channels. You have explained it very well. Thank you a lot!!! The way you compared unbuffered channel to a portal was epic.. I wish everyone explains concept like you.

[@akmzahidulislam2764]

Brilliant work, Ryan. Deeply impressed

[@winsonwardana28]

Thank you for choosing words that can be understand by human 👍👍

[@blueice1364]

You are a great teacher. No one out there explained Go in such simple yet elegant way. Thank you!

[@nwxxzchen3105]

I should must give this content a thumbs up, channel, context, interface you give us the most clear explanation in the whole universe.

[@s-guytech9160]

I mistakenly un liked because I did not know I already liked it before. Cool stuff, Great Explanation.

[@visa2256]

Thank you Ryan, I love the way of your teaching, its pace is very smooth and gentle, not only you deliver the explanation clearly, but also make it easier for us to digest.

[@marnesh2008]

you should become a golang trainer or teacher, this is the best explanation video so far

[@samiurias]

Incredibly good explanation! :D Thank you very much! 😊

[@WaldirBorbaJunior]

Man... what explanation. Sincerely the best one.

[@ianlogan3055]

I really like the way you explained channels, nicely done!

[@solar2361]

Love it. While you are teaching from your bed. I also watching from mine.

[@user-ey6zi9jt5s]

Ryan is the Laurence Fishburne (of "The Matrix" fame) of Coding. So smooth, assured and comfortable with the subject matter! Completely agree that training orgs like ACouldGuru, OReily etc could utilise his unique skillset and approach!

[@f00b4r123]

Excellent explanation. Thanks!

[@nsgirish]

Excellently explained. Thanks sir

[@linamoussadek6467]

BEST VIDEO !! Deserves so many more likes omgg

[@pss_crs]

Why KZbin algorithm Doesn't support channels like Ryan instead of Music or fake pranks. I was very impressed with the way you convey knowledge. If you do courses for sale, I will be the first to buy them

[@thenomadchronicles]

This was the best video that I watched that makes me really understand Interfaces. Thank you so much!

[@reanimatedmanx]

I'm going to repeat other commenters, great voice and explanation, very pleasant to listen. GL on the channel! Subscribed

Great work on this! 🔥

[@sondosabd9474]

Thank you very much for this tutorial

[@solojazz75]

Ryan, this is one of the most useful video I have seen on this topic. Thanks. a quick question, I need to collect data from multiple wss, and sort of concatenate the data, do you think a channel would be good for that? (think market data). Cheers

[@kapo5636]

You should do a lot more of coding from your bed setup. It is very relaxing to learn from you! I definitely learned a lot

[@someone5781]

This is a great explanation Ryan! Would you consider making a full golang tutorial? :)

[@khayrulislam752]

So helpful. Please make a playlist.

[@kasoivasoy7808]

Thanks, Morgan!

[@markcampanelli]

Thanks for the great explanations. My only issue is that the Wells Fargo bank account didn’t have any fees. That’s completely unrealistic 🤣.
