I never seen, how easy explanation of callback function you have made, It is seriously the best and most clear definition of callback in TH-cam and Paid course.
for those who who still do not understand the code. 04:00 1. sayHello function - it prints the same value which will be passed as argument while calling the function. 2. add function - it has 3 arguments - num1 , num2 and callback a). it prints the sum of num1 and. num2 b). called function named callback() - the confusing thing here is that callback function is not seen declared than how it can be called so the answere is : when calling the function add() we have passed three arguments so the arguments when replaced the parameters we got to know that this function is printing the sum of 10, 20 and calling function sayHello() and since sayHello() is declared that's why the 7th line is written such that to just call the above function, this code is meant to replace the parameter (in this case 'callback') with the argument of function name (in this case 'sayHello')
Bro seriously! I wanted a revision on this callback and when i checked other videos it was quite confusing. But, you explained in such a way that, no possibility of forgetting the concept . Thanks Bro🙂. Kindly make react.js videos (if possible).
ya, i too find tech gun videos teaching or explaining in simplest manner than others due to which i clearly understand at first watch only. Thank you sir for your effort 👍👍
Simple and Short...Other videos were so confusing, but you explained in such a way that it was clear and cut...thank you..! Keep on the great work....!
at 5:54 you are telling that we can't pass another function directly but below code us executing without any error function sayHello(){ console.log("hello") } function sayHi(){ console.log("hi") } function add(num1,num2) { sayHi() sayHello() console.log(num1+num2) } add(30,40)
Sir if I'm not wrong, while defining a function or method those variables we give as inputs are called parameters. And while calling that function or method , those values we give as inputs are called arguments, the actual values. Am I correct?
Sir direct v function bana k call kr ra hu 1 se jyada kitne v tb v call ho ra h output aa ra h apne bola ki ni ayega or fir jab direct aa ra h to callback function ka kya fayda
But, both functions "sayHi, sayHello" are also called into add function. Its worked. I actually did not understand what do you mean? The DRY concept does not follow if I call two functions, are you actually mean that?
sir I am a beginner mujhe ye smjh nhi aarha h k hmne callback k name se jo parameter bnaya h phr us function k undr jb callback lkha h t uske sth paranthesis q lgae hn qk hm paranthesis t function k sth lgate hn r callback k name se to hmne parameter bnaya h function t nh t phr parameter k sth paranthesis q lgae hn?? kindly guide me.
kyuki us callback ki jagha ek function recive ho raha hai aur hum log paranthesis lga kar us function ko call kartey hai. Tum chaho to pahley ek console.log(callback) without paranthesis lga kar dekh lo ki waha kya recive ho raha hai. Tumko ek function dikhe ga

Way more understandable than any other youtubers!💯...simple is effective rather than showing themselves as they know everything!

04:00
1. sayHello function - it prints the same value which will be passed as argument while calling the function.
2. add function - it has 3 arguments - num1 , num2 and callback
a). it prints the sum of num1 and.
num2
b). called function named callback() -
the confusing thing here is that callback function is not seen declared than how it can be called so the answere is : when calling the function add() we have passed three arguments so the arguments when replaced the parameters we got to know that this function is printing the sum of 10, 20 and calling function sayHello() and since sayHello() is declared that's why the 7th line is written such that to just call the above function, this code is meant to replace the parameter (in this case 'callback') with the argument of function name (in this case 'sayHello')
callback function was a pain in the ass for me.Thank you for clearing it sir you are awsome♥️
Bro seriously! I wanted a revision on this callback and when i checked other videos it was quite confusing. But, you explained in such a way that, no possibility of forgetting the concept . Thanks Bro🙂. Kindly make react.js videos (if possible).
