Bro Now I have got a job in Wipro.... Remembering those college days when You were one and only teacher for Now as my job field is in network.... Missing your videos thanks for those days but recently I am thinking of learning DevOps & Automation.. So if you come with such a video on this topic... It will be too much helpful....

harry sir you CAN change the 4th character in in string by replace method, ofcourse it will not change the actual string but you can display the change in string and also you can make the copy of it by the replace method

[learner]

In the first question, '4' will be printed !
Great tutor! Thank you harry! You rock always! 🤘

Hi for last question I changed string to array and it worked because arrays are mutable -
const arr = [...str]
for(let i = 0 ; i < arr.length ; i++){
if(i === 4){
arr[i]='o'

console.log(arr[i])
}

}
console.log(arr)

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.

Problem 1 - Answer - 4 because escape sequence chatracter is not included as string
Problem 3 -
let string1 = "Hi, This is Siddhant"

[samirop]

Tips: You can use this code to convert input data into number in single line
let sam = Number.parseInt(prompt("Enter here:"));

[kalpu]

Problem 1 : answer is 4.
Reason: Escape sequence characters are counted as single character.

// Q.5 - Change a particular letter of a string
let actor = "LeoDeCaprio"

// method1 - incorrect
actor[3] = "L"
console.log(actor)

//method2 - correct
console.log(actor.replace("De", "Le"))

[Ithinktoons]

Harry sir, I have a solution for 5th question;
5)Try to change 4th character of a given string were you able to do it?
let d="Kavin"
console.log(d.replace "n", "f")

[shaktiswarupmishra]

Sir, we also can slice the number like this

str = "Please give rs 1000"
matches = str.match(/(\d+)/)
if(matches){
var amount = (str.slice(matches.index))
}
console.log(amount)
console.log(typeof amount)

[Yug.]

Sir aapne last question me kaha ki string change nahi ho sakti but
We use..
let str="harry"
Console.log(str.replace("r", "i"))
O/p : hariy

[umairraza]

In the first question the code will print 4
