function callBackFunc( callback ) { callback(); } Function which are passed as a argument to other function and can be called callback function. #Great
I really like the way you explain things, you help me with my whole journey while I was learning web development. I will be very appreciative if I do something for you.
const per1=(friend,callfrnd)=> { setTimeout(function(){console.log(`i am busy right now i am talking to ${friend} `)},3000); callfrnd(); } const per2=()=>{ console.log("this is second function"); } per1("shivam",per2); is me call back function ne kam kyu nahi kiya,isme pehle per2() function ka output show ho rha hai, 3 sec baad me per1() function ka output aa rha hai,but according to callback function ,pehle per1() and baad me per2() execute hona chahiye na ? comment if anyone can explain this
hello sir, I request you to explain the callback function with timer example mentioned at the beginning of the video. second example me calback use kar ke kuch achive nahi hua.
callfrnd is working as a parameter, When perTwo()function pass to perOne as a argument function. Then callfrnd is act as a function due to perTwo() function. That's why it define as callfrnd();
callback ke liye perTwo ko perOne me pass karney ka jarurartt kya hai... bina pass kiye bhi toh direc call kar saktey hai na perOne ke andar se ? someone pls explain this.......
Callbacks are a way to make sure a certain code doesn’t execute until another code has already finished execution. So func A executes and is completed only then func B (say callback func) will start executing. So this concept is called Synchronous javascript code in your video 50 ruclips.net/video/tBmeblr67U0/видео.html. So why Callback functions fall under Asynchronous javascript topic rather than Synchronous javascript topic?
There is no need to pass the perTwo() as an argument of perOne(). If we can directly call perTwo() in perOne() body it still work. Can someone explain??
@ Thapa Technical bro please clear my doubt: when to use and when not to use one over other:----- function declaration, or function expression or arrow function
Thapa bhai thank you soo much, your video helped me soo much, ap se ek request hai CALLBACK KA REAL WORLD EXAMPLE bhi batao do na, i mean real programming ki ek example...aur bahot acha explain karte ho lekin thoda sa calm rhne ki koshish kiya karo samjhate time. Followed u on insta too

I am calling you back. I am calling you back dakha. Why ${friend} method not working

function abc(name,second){ setTimeout(function(){ console.log(`this is first ${name}`); },3000);second(); } function xyz(){ console.log('this is second funciton'); } abc("function",xyz); is me call back function ne kam ku nahi kya 3 sec bad dosra function ana chye tha magar ye to phle hi show hojata hai console me
function a() { setTimeout(() =>{ console.log("hello") ; b() ; }, 3000) ; } function b() { Console.log("india") ; } a(); b(); Without passing function this program also run then why we are passing function

You make it very simple. Thank You !!!
Nice example👍
hello sir,
I request you to explain the callback function with timer example mentioned at the beginning of the video. second example me calback use kar ke kuch achive nahi hua.
I got stuck on call back function i your video explain it soo good
Congratulations bro for 100k subscriber
Thanku so much ☺️
I have a doubt ..you have not defined callfrnd function where is the definition of the function?
callfrnd is working as a parameter, When perTwo()function pass to perOne as a argument function. Then callfrnd is act as a function due to perTwo() function. That's why it define as callfrnd();
Thank you so much....u really make it simple♥️♥️♥️♥️♥️

same query here, what diff it makes, other than that what if we call callfrnd function in the first line itself in the perOne function
Thank you so much sir 👍

how to select funA together, ant shortcuts plz reply

perOne("Thapa", perTwo)
In this code why perTwo() is not written. Why perTwo is not forwarded by parathesis ()?
We are passing it as an argument not as a function.
@@アマン-l8w ok. I was confused in that part.. thanks
Thanks Bhai
that means one function in an other function called callback function
sir please make video on promises , async await
Boom Guys!
const perOne = (friend, callfrnd) =>{
console.log(" I am busy right now. talking to ${friend}. I will call you back. ");
callfrnd();
}
const perTwo = () =>{
console.log(" I am calling you back dakha.");
}
perOne("Zohair", perTwo);
but output in the console
I am busy right now. talking to ${friend}. I am calling you back.
I am calling you back dakha.
Why ${friend} method not working
` iska use Karo na ki " iska
this is not work with setTimeOut function
Thanks

function b() {

Without passing function this program also run then why we are passing function
