Harry Bhai, Mai ek baat puchna chahta hu, 3rd Ques mai agar hum "Try Again" i=prompt(Enter a number) ke baad lagate hai toh correct number entered krne ke baad bhi ek baar print ho jayega and agar hun "Try Again" i=prompt(Enter a number) ke pehle likhte hai toh pehli baar puchne se pehle hi ek baar "Try Again) Print ho jayega. Toh is problem ko kaise solve kiya jaye. Thanks for this Wonderful Course.

loop mein let samajh nhi aya

[@hokorashi_6283]

I am a bit late here, just wanted to say ur tutorials are awesome thanks for helping me follow my passion. Also wanted to add a bit that in the problem no.3 u can see that everytime u execute it says try again first than asks user for a number. U can over come that by nesting an if else statement in while loop. i tried it and works like a charm. Here is the code : let n = 4 let a while(a != n) { a = prompt("Enter a number") if(a == n) { console.log("You wrote correct number") } else { console.log("Try again") } }

[@Netpilation]

let correctNumber = 122 while(true){ let typeNumber = parseInt(prompt("enter the numebr::")) if (typeNumber===correctNumber) { console.log("you entered the correct number>>") break } else{ console.log("the number you entered is incorrect") } } i did it this way and it is way more optimized than yours

thank u brother ;)

@@Netpilation but if the no. is incorrect USER is not allowed to enter the correct no. again ... and in the question it is mentioned that ... print untill the user enters the correct no.

just use ... alert("try again") instead of console.log("try again")

9:16 you can do it like this => let cn = 4 let i; while(i!=cn){ i = prompt("Enter a number") if(i==cn) { console.log("You have entered the correct number") } else { console.log("Try again") } }

[@Yenoke]

@@rayyanbhattibhatti7772If I am not wrong, ths number is fixed, 200 you could have also done let number = Math.random() Or let number = Math.floor(Math.random() One of these two will work I don't remember So it chooses a random number so the guessing number is not same Correct me if I am wrong

To remove the try again during the start in problem 3, it's better to use if else. Like this let cn ="Harry Bhai"; let i while(cn != i){ i =prompt("Who is the Best KZbinr") if(i !=cn){ console.log("Galat Zabab, Try again") } else{ console.log("Correct Answer") } }

It can be also done by for of loop

[@outofspeedyt2589]

I did the same thing LOL

[@NamorFunctionStore]

@@UjjwalMishra_68 no you cant use for of loop for objects The for...of loop is used to iterate over the elements of an iterable object, such as an array, a string, or a map. However, an object in JavaScript is not an iterable object, so you cannot use a for...of loop to iterate over its properties.

Harry Bhai, i would say at first when i started to learn the basics of web development from your channel, i often found out that you frequently say that you guys could do this on your own and as i was a beginner, things started to distract me from my path, i left learning and thought that there is not even a single person on youtube who wants the beginners of my age to learn how to code and everyone is just running for views and subscribers, but since i have accessed your current JS playlist, i would say that you are teaching with much more honesty than you did before. Keep up the good work. Always remember that there are people who don't say a lot but keep watching you and they feel themselves inferior in terms of their mental capability and they are afraid of writing comments, so to avoid humiliation and mockery from your young students, so when you teach, please make sure that you keep the slowest guys in mind. Hope you understand. Regards, Taimoor Khan, Punjab, Pakistan

Great course. One minor mistake in question 3. You can see try again getting print even though the user hasn't entered anything yet.
