A Variable is like a container that holds some value and the value can change/vary in later in the program. Three ways to create variable: - var (old way) - let & const (modern way) var variable has function scope, whereas let & const has block scope. var variable are hoisted whereas let & const are not hoisted. Good explanation keep up the good work 👍👍
hello Anurag .. i am from bangladesh your video just wow .. i saw many javascript course on youtube but its javascript course world best . and its underrated youtube channel. i wish this channel very soon 1M Subscriber .
Mere sare course jo bhi UA-cam per hain humesha rahenge. Aage chalkar Node.js, Mongodb, Express.js, Typescript aur bhi courses aayenge. Mera goal hai ki ham India se ek skilled youth ko produce karein jo ki har company ke liye ek asset hon. Na ki desh ke upar hi bojh ban jayen. Aur agar aise ki apka support raha to ham zaroor ismein kamyab honge 😊
I tried foreign UA-camr's courses for JavaScript but none of them could explain like you do. To be honest it is very rare for me to comment on a video like this. But honestly man this needs some appreciation. You're doing great. I hope you get successful in your UA-cam journey. Also you've provided subtitles in English. Mad respect man. I would suggest you to translate and upload these videos in English and other languages too, to get global audience.
Very Nice Sir One Of the Best Teacher Javascript . Jo bhi aa rha hai pura video dekh ke ja rha hai . Maine Abhi Tak Aisa video nhi dekha ❤❤❤❤ I appreciate you sir | Jai Shri Ram 🙏🙏 |
At first I really did not wanted to follow this course because of its length.. but after watching couple of initial videos .. I realized that it is really good to have an elaborate and clear knowledge of concepts and fundamentals for long time journey.. I am finally following your course now. Very excited to finish the course, and be able to build really good projects with javascript.... Thanks for this playlist, it's really a gem.. for me❤
Hello sir, You are just awesome, After watching your third video of variables, I am somewhat confident that I can learn JavaScript as I'm coming from a non-it background. Thanks much for your kind support.
i am following all the lectures and i hope when i complete this and made my name in this i am gonna request to take be interview by sir anurag!!!! big respect sir🤩🤩
I started this playlist today day 1 I know basics of javascript so I will binge watch basic part and if I found any topic which I don't know then I will try that topic
Anurag sir you teach so well, I just completed this video and I'm now convinced how variables work in JS. All thanks to you and your teachings, thankyou so much😀 Just a request can you provide some source or recommendations for practicing your topics as I prefer ChatGPT and other stuffs Sir! But, do you have some other and If so then please recommend it to me Sir! peace.
one of the best courses out there on youtube, Highly Appreciated sir, I am learning Javascript to land a fresher job in Mern Stack, I would surely like to follow you to the end sir! Bundle of Thanks
I had watched so many videos for the javascript course but your lecture among them is one of the best i can say. I highly recommend your lectures to one who is starting with the programming and want to be pro in it. Also there are answers to the questions that were asked in the interviews, that adds a advantage to this tutorial. Thank you so much for this Javascript course. Looking forward to learn more with this series.
Hello Anurag Ji, Thank you for explaining the differences between let, const, and var in detail. I look forward to learning more about their specific uses and best practices. If I have any questions, I'll be sure to reach out. Love u
Ye to bahot achhi baat hai ki tumne HTML aur CSS poora complete kar liya hai, aise hi seekhte raho. Aur JavaScript videos dekhne ke saath saath CSS ke khoob saare projects banao taaki CSS ki practice hoti rahe. Keep learning and sharing 😊
Here i just felt so awesome and proud that you pronunced the word Kannada correctly🥰. Also Thank you for such a good course, i have just started it is interesting.
The third difference between var and let is that, a variable declared with "var" can be redeclared but with "let" we can't redeclare a variable in the same scope or block.
A variable is a name in which we can store a value either string, number, boolean, undefined, null, bigint. A variable can contain any of the following character but not start with digit(0 to 9),but start with two special characters $(dollar) and _ (underscore)and a normal characters (a to z or A to Z) .There are three types of variable Var,Let,Const,var is a function variable and let & const are scope variable.
At 34:15 , sir, in JavaScript, when a script runs, every variable initially receives the data type of ‘undefined’ during the memory allocation phase. After this phase, the script proceeds to the execution phase. During execution, variables that already have values retain those values. However, variables that do not have any assigned value remain ‘undefined’ by default, as they do not receive a value from any variable during the execution phase.
let , var , const diff let , const are work within blocked but var is function code can access any where 2- diff var can acces before initialise before declacration but not in let and const
25:05 Assignment Done let fName = "Sarim"; let lName = "Hassan"; let Age = 20; let mySelf = "My Name is " + fName + ' ' + lName + ". I am " + Age + ' ' + "Years Old."; mySelf;
let and var me difference let block scope hota hai and var function scope hota hai and secound difference var key word se kisi ko difine kiye hai to usko pahe print karwa sakte hai par uski value nahi ayeg par yo error bhi nahi dega aur let ke case me error aa jaye gi
Because it's a new channel Bro. I have started this course in September of this year itself. Many students need this content but they don't know that this channel exists. Now it is your and other subscribers responsibility to propagate course between the students who need this.
before initialize console =====> 1.let is getting error before initialize and 2.var is get value undefine 3.const in can not change the value and best way to use with const variable
