// callback = a function that is passed as an argument // to another function. // used to handle asynchronous operations: // 1. Reading a file // 2. Network requests // 3. Interacting with databases // "Hey, when you're done, call this next." hello(goodbye); function hello(callback){ console.log("Hello!"); callback(); } function goodbye(){ console.log("Goodbye!"); }
exactly always got me lost when other youtubers keep on repeating something like, we put another function inside a function as a paramether and in the function block we call back to the function a callback function, that is why it is called a callback function. And then they continue on giving an example of either a function with another function as parameter, or array functions console logging the elements when iterating through the elements. Like why would console log be a callback function, they never explain, This video explains everything to me. Thanks!!!
Anytime I'm learning something new and struggling, I watch a BroCode video and walk away totally getting it. I LOVE how everything is clear and concise and not a lot of needless rambling.
Finally, I understood this. The concept was very confusing when others tried to explain it, and this video made it very simple to understand. Thank you for breaking it down.
One thing I believe could have been clarified is that callback() does not actually WAIT for the line of code above it to be done. If the line above is asynch, it will call callback() first.
Thank You so much before this video I was not able to understand this concept , I am now able to understand better .... Pls provide more such informative videos like this... ❤
Hi, okay, I want to congratulate you for this incredible work, where you share your knowledge. I want to ask a question about how I render the results of the code in the console, so I know how to do it with HTML
Add the relevant script tag in your HTML file and set the src to your javascript file, then go live from your vs code, then navigate to your console in your browser, you will see the changes rendered as you code.
So what's the difference between using a function as callback and just calling the function from inside the one which will take some time to finish? Wouldn't this accomplish the same thing? Thanks for the video!
Both works same in most of the cases but there are some points to be consider: 1 ) callback program flow is more controllable 2 ) asynchronous operation execution for e.g in video goodbye is executing later if we write normal hello function and call goodbye function in hello function and after calling goodbye function write another code then if goodbye function takes time to execute then other code after goodbye call will also has time delay . which is not happen in call back case . HOPE THIS HELP : )

function hello(callback){

Honestly callbacks really left me confused. This is by far the best explanation I’ve watched. Tysm ❤
True
Bro, this was the easiest explanation I've ever seen. Thank you!
I love how you explain complex topics like this. You really helps me a lot.

Fell like I'm finally understanding js. Thanks BRO! Greetings from Colombia!
Thank you for those example codes. Those really help with understanding the concept in-and-out of the box.
one of the greatest explanation i have ever seen
You explained this in the simplest way possible bro! Now I love the “Bro Code” Channel!
Finally, I understood this. The concept was very confusing when others tried to explain it, and this video made it very simple to understand. Thank you for breaking it down.
Such a beautiful explanation, Bro...earned a sub!!
@BroCodez : an impressive way to teach...
A lot to learn in just 7 minutes

THANK YOU SO MUCH😭. I really needed this⭐
Your videos helped me understand JS although i have already watched a lot of videos on JS. Thanks Bro!
Thank You so much before this video I was not able to understand this concept , I am now able to understand better .... Pls provide more such informative videos like this... ❤
Thanks for this wonderful explanations I understand this in easy way thanks bro🎉

Great explanation 👍
So what's the difference between using a function as callback and just calling the function from inside the one which will take some time to finish?
Wouldn't this accomplish the same thing?
Thanks for the video!
I have the same question or is that even a callback function too?
Both works same in most of the cases but there are some points to be consider:
1 ) callback program flow is more controllable
2 ) asynchronous operation execution for e.g in video goodbye is executing later if we write normal hello function and call goodbye function in hello function and after calling goodbye function write another code then if goodbye function takes time to execute then other code after goodbye call will also has time delay . which is not happen in call back case .
HOPE THIS HELP : )
good explanation!
if you had explained it using the setTimeout function itself it would have been much easier to understand i think , but thankyou.
Truely you're the best.
This is my seal. I have watched the entire video, understood it, and I can explain it in my own words, thus I have gained knowledge. This is my seal.
this was the video that finally helped this click with me. thank you!!!
i got it, thank you your the best !
bro i am not understanding the callback since yesterday after ur explanation i m going to subscribe u ASAP!!
cool
Thank you ❤
legend
Thanks Bro!
Thank you
legend!!
this guy is insane

// LOVE YOU BRO CODE THANKS YOU!
But if you use the setTimeout, then even with callback, bye is displayed first.....what's happening here?
best
Django course please
still confused.
Goat!
Thank you bro code
This callback function seems complicated.
Hi bro code please make small small project using function object array
chad
Bro Django please 🥲
What is that , is it good?
@@hungry_khid1007 Yes, of course. It looks like python
Bro react
HI BROCODE THANKS FOR THE VIDEOS WHERE CAN WE CONTACT YOU ?
nice explanation!
thank you
Thanks Bro!!
