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!!!
Honestly callbacks really left me confused. This is by far the best explanation I’ve watched. Tysm ❤

Bro, this was the easiest explanation I've ever seen. Thank you!
You explained this in the simplest way possible bro! Now I love the “Bro Code” Channel!
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!
Such a beautiful explanation, Bro...earned a sub!!
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.
This was very helpful mate. Thanks! Appreciate your work.
Thank you so much for making it so simple and understandable ❤
Your videos helped me understand JS although i have already watched a lot of videos on JS. Thanks Bro!
one of the greatest explanation i have ever seen
@BroCodez : an impressive way to teach... A lot to learn in just 7 minutes Love from Lahore, Pakistan
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 explaining callback function.
liked the way u explained things so simple and clear keep posting 💌
this was the video that finally helped this click with me. thank you!!!
the most simple and human understandable explanation thanks bro code
And i finally understand. Greetings from Ireland x
You're the best, love from argentina!!
good explanation!
What do you know about promises? Would be interesting to see something about it!
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.
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.
if you had explained it using the setTimeout function itself it would have been much easier to understand i think , but thankyou.
Thanks Bro!!
thank you

this guy is insane
cool
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?
@Shubh_R_M

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 : )
Thank you bro code
