Thank you for making such a beautiful javascript tutorial. Because You teach the actual javascript which is necessary for actual production development need. Very Very thank you. I will share your channel as much as possible to everyone. I really like your teaching style and I aslo need that type of javascript teacher. God bless you.
hello sir, I am from Pakistan I have no knowledge about coding, but I want to learn, I watch your html playlist, CSS tailwind playlist and now I am watching JavaScript.
In JavaScript, you cannot traverse from a higher negative index to a lower negative index using the slice() function or any other standard string method. The slice() function, as well as most other string methods, expects the start index to be less than the end index when using positive indices or zero-based indices. When using negative indices, you can only traverse from left to right (from lower negative index to higher negative index) or from right to left (from lower positive index to higher positive index). You cannot reverse the start and end indices when using negative indices with slice(). const myString = "Hello, World!"; const slicedString = myString.slice(-1, -8); console.log(slicedString); // Output: " " const myString = "Hello, World!"; const slicedString = myString.slice(0, 5); console.log(slicedString); // Output: "Hello" const slicedStringNegative = myString.slice(-6, -1); console.log(slicedStringNegative); // Output: "World"
Very practical, Application oriented simple explanation ,This seems different to me ..I hope you will make more useful videos.. -best wishes and_Thank You.
original string is gameName and when you change gameName to uppercase, then the original gameName still becomes the same because first value gets stored in stack and only copy value changes. Please see the previous lecture of datatypes summary(primitive and non-primitive) to understand.

@@TechieHeish1-bm2nd when you define using new its a non primitive data type bro. sir didn't tell this. check internet or stack overflow
@@honblegaurav9917 Exactly my question! why did it not changed?
Got it! it is non primitive when define using new String(). String is an object

A point that should be noted from the video is when sir said that ,"Strings are the most powerful in any programming language".
@chaiaurcode
Const count = ( apna_naam )=>{
return apna_naam.times()
}
Count(apna_naam) > Count(dusaro_ka_naam) ? "Hitesh bhai 😂" : "aam janta 😂" ;

Crazy explanation understand everything 👍🏻👍🏻👍🏻👍🏻 thanks sir...

Sir i watched many of youtube tutorials of JS but you Playlist of Js is the best ever ... thank you soo much sir love from pakistan
Old way:
Let a = name
Let b = age
let a = prompt("What is your name");
let b = prompt("What is your age");
document.write("My name is " + a + "and i am " + b + "years old")
New way:
let a = prompt("What is your name");
let b = prompt("What is your age");
document.write(`Hello my name is ${a} and I'm ${b} years old `);
We use ` ` to write complete string and will use ${} to inject variables in it.

const myString = "Hello, World!";
const slicedString = myString.slice(-1, -8);
console.log(slicedString); // Output: " "
const myString = "Hello, World!";
const slicedString = myString.slice(0, 5);
console.log(slicedString); // Output: "Hello"
const slicedStringNegative = myString.slice(-6, -1);
console.log(slicedStringNegative); // Output: "World"

lov your teaching method
great video
Code to yaha hai Par Chai 😂 kaha hai Thanks sir padne mai mja aaya
very conceptual video sir
Strings are immutable in JS so those methods return a copy of that string after performing operation.
It seems like sir is standing while recording it . Great Content🙏

Kindly consider creating a TypeScript series in Hindi as well
Here is the all important methods of String
let s = new String("Chhaya"); // here string s is an object
console.log(s.toLowerCase()); // in lowecase

console.log(s.indexOf('y')); // return index from beginning
console.log(s.lastIndexOf('a')); // return index from ending position
console.log(s.length);
console.log(s.slice(0,4)); //print string from 0th index to 3rd index as ending index is excluded
console.log(s.substring(0,4)) // Similar to slice but can't take negative value as an argument
console.log(s.charAt(1)); //print char present on given index value
console.log(s.includes("Chha")); //If given input present then return true otherwise false
console.log(s.includes("shaya")); // return false
console.log(s.endsWith("aya")); //return true if string is found from last
let url = "www.userid?20.com"
console.log(url.replace('20', '-')); //replace 20 with underscore
let word = "Chhaya is Shanaya and she is a baby girl";
console.log(word.split(" ")); // return all the words from given string in the form of array
let name = "Shanaya"

reference mil raha hai bhai memory ka copy nhi mil rhi
Bhai Bhai Bhai ese av tak kisi n nhi padaya even mene bhut javascript k videos dekhe but you are the best.

originial value change nhi hua hai cause wo stack memory mai store hai and usmai ek copy ko pass kiya jata hai direct referen ce ko nahi
