Learn JavaScript CALLBACKS in 7 minutes! 🤙

[@BroCodez]

// 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!"); }

@BroCodez Django course please

[@Blitz61wasd]

Bro i subscribed and liked can you make django course

[@-_SleepAndEat_-]

Bro can you do Kali Linux ?

[@1992daven]

I love the way you explain. Those other youtubers had me lost.

[@thatlastborn]

Right!!!

[@jimmyhaotran123]

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!!!

[@isaiahaguilera7973]

Bro, this was the easiest explanation I've ever seen. Thank you!

[@a1m4thah3d]

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.

[@thatlastborn]

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

[@tayangantengahmalam2480]

True

[@masterwitcher317]

I love how you explain complex topics like this. You really helps me a lot.

[@vallunacoder.wecodetogether]

[@saichaithrik7134]

one of the greatest explanation i have ever seen

[@r3dwulf3]

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.

[@3lirez]

You explained this in the simplest way possible bro! Now I love the “Bro Code” Channel!

[@mohitanand5646]

Thank you for those example codes. Those really help with understanding the concept in-and-out of the box.

[@piotrmazgaj]

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.

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... ❤

[@sridhararivazhagan1323]

Thanks for this wonderful explanations I understand this in easy way thanks bro🎉

[@ColeHartman1]

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.

[@zine-el-abidine]

i got it, thank you your the best !

[@elzosantos1253]

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

[@gloryanoliefo]

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.

[@andrews13]

You are the best!

[@hasanatahmadzai9079]

Truely you're the best.

[@brijeshkumarchavda]

Thank you ❤

[@jadad7296]

cool

[@johnwayne8059]

What do you know about promises? Would be interesting to see something about it!

[@johnnyenglish3867]

legend

[@otisprogramming2437]

Simple explanation, however I found the example of setTimeout to be open to misinterpretation or a little misleading. If we invoke the callback goodbye after a setTimeout function, the callback would still be logged first. I think due to setTimeout using a callback itself which interacts with the event loop and event queue.

[@girishph.9970]

if you had explained it using the setTimeout function itself it would have been much easier to understand i think , but thankyou.

[@rx808]

randomComment() // LOVE YOU BRO CODE THANKS YOU!

[@mohammadalsallal7977]

this guy is insane

[@deeplife9654]

we need call-back mechanism to ensure that one function is called after another function sequentially ?

[@kathikr9360]

thank you

[@ArthurWM9]

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!

[@jesusjosemarthalaborin1014]

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 : )

[@abdoun8214]

still confused.

[@alirezafarokhzadeh]

hi, and thanks for your videoes, I have a question: why the folowing code didn't work correctly? and show "two" befor "one" one(two); function one(callback) { setTimeout(() => { console.log("One!"); }, 4000); callback(); } function two() { console.log("Two!"); }

[@Blitz61wasd]

Django course please

[@shauryasingh63]

Thanks Bro!!

[@7calculus]

But if you use the setTimeout, then even with callback, bye is displayed first.....what's happening here?

[@LaughThyself]

i think setTimeout will run only after callback is done, this is 3 mo idk if it helps still

[@Ajinkkyaa_naik]

Been banging my head over this since a week. LIke I understand the whole concept but always failing to put it into use. the creation is not coming to me automatically and organically. Any other ways I can improve writing callbacks? the difficulty I am having is the writing the whole thing in a correct order. I have seen many coders write this differently.

[@spencersedano]

Thank you bro code

[@jay70p]

is it AJAX ?
