Text won't be visible as clear as now, this is common issue which can be avoided.

[@sshreeeditz640]

Black theme is most recommended to use for programmers while coding. But when its came to teaching, White based themes are better because in black theme we can't see the texts clearly.

[@batambuzestephen8243]

Hi Navin. I checked the escape character makes a vertical shift for windows instead of \v.

[@jno1lilno]

so helpful thank you so much

[@sr-sunny-raj]

Sir you already had made a playlist for javascript named JavaScript Tutorial for Beginners , then why another playlist for the same. Can i go with that or should i wait for you to upload all the videos?

[@hemanthar8363]

Thanks manh helps a lot

[@navyasrisirigineedi6430]

Sir , I guess , we got output as "object" when typeof(user) when given user = null ; because null itself is a special function with in Javascript to change any variable or any object property to null when assigned. So , In this case user is treated as an object with null as a function in it.

[@sanjeevkumarambati]

fantastic line in this video is ' null represents an object but it is not actually an object '

[@shashankkumar8505]

Waiting for next video 🤠

Hey you are just amazing

Grt jS series

[@prernadhiman6471]

bang! strange to see that semicolon in js makes no sense. It didn't effect the output in this particular snippet- "console.log("bleh")"

[@kovurudhanush8209]

🤣

[@sivanms918]

It's not semicolon it's single or double quotes..

[@donkris2062]

good work mate! is easy to learn JS from your course than pronouce your name ;)

superrrrrbbbbb platform for learning programming language. @TELUSKO

[@vinoths5753]

please do videos for js in web development

[@funwithscienceezhilan9550]

Sir is it necessary to palce a semicolon at end of functions because u placed at end of console.log

[@teluskosupport1]

//because js is not a compiled language it is interpreted language so it will not throw error if we are not using semicolon but it will not work as expected so we are using semicolon to avoid any error in js //what error should come if we are not using semicolon in js //it will not throw any error but it will not work as expected so we are using semicolon to avoid any error in js and it will work as expected in js //therefore it is recommended put semicolon after every expression and statement e.g 'use strict'; //put semicolon after that let print=function(){ console.log('shiva'); }; //put semicolon after that

[@liveforweekend8264]

Hey Navin, i have been watching your videos from long time your python course was phenomenal. I have question what is the difference between VAR and LET, Can we use Var instead of Let? Thank you in advance!!

[@matildakpolley6926]

Let does not allow variable to be accessed outside the scope, any variable declared using let is accessible within the function or code of block within which is defined in while any variable declared using var keyword is accsessible outside the scope. So in all I would say let is scoped while var is not...

[@teluskosupport1]

'use strict'; console.log(a); var a = 1; var a=4; console.log(a); // console.log(b); //ReferenceError: let b=2; // let b=5; //error //using var keyword we can redeclare the variable //using let keyword we can not redeclare the variable // var can be hoisted and let can not be hoisted //hoisting is a javascript mechanism where variables and function declarations are moved to the top of their scope before code execution. //using var you can use the variable before it is declared //but using let you can not use the variable before it is declared

[@raunakvhardwaj9025]

yes vertical space work in Mac.

You just confused me... About null... 😅😀... But great explanation ...

[@YashSharma-op5mv]

greattttttttttttt

[@shashankkumar8505]

Sir what is difference between var and let???

[@teluskosupport1]

//run this program and read the comment 'use strict'; console.log(a); var a = 1; var a=4; console.log(a); // console.log(b); //ReferenceError: let b=2; // let b=5; //error //using var keyword we can redeclare the variable //using let keyword we can not redeclare the variable // var can be hoisted and let can not be hoisted //hoisting is a javascript mechanism where variables and function declarations are moved to the top of their scope before code execution. //using var you can use the variable before it is declared //but using let you can not use the variable before it is declared

students who learnt python on their higher school or commonly devs from python background java script is familiar and does not look unfamiliar

[@MuhammadHamza-pv3fl]

please add a js library in this javascript tutorial like react or react native plzzz don't ignore my comment I have watched your python tutorial now i'm learning this js series from Pakistan

[@zindagigulzarhai7338]

Hello sir, I want to built-up my carrier in Web developer, I am having my certificate in JavaScript, i don't have any technical background, is it possible to get job... Plz reply...

[@DeepakGupta-pz4fx]

@Sanya I suggest you first you complete Javascript learn after that you learn React and Node JS ...it would be help for job now React is most demanding technology.

[@asamveerareddy8690]

Sir in yesterday class we are using the string's like var s="veera's" and not using the single quotes but var s='veera'\s' this is possible sir

Yes Escape character. Mentioned that in the video

What is the difference between document.write(); and console.log();

[@teluskosupport1]

when you add your script.js file to your html then you got clear differnce automaticlly The main difference is that document.write () inserts text into the document (the webpage in the browser window); console.log () does not. The user cannot see what is logging to the console as that is another interface, separate from the HTML/CSS environment.

[@anamikasingh1783]

His videos helped me alot in interview preparation, thanks a lot @telusko 🙏

[@deeptiranjanswain79]

In my system the output of console.log(typeof 5/"abcd") is also showing NaN

[@SathishB153]

you should put 5/ "abcd" inside a parenthesis() in order to get number as output. console.log(typeof (5/"abcd") ) output: number

[@teluskosupport1]

it is correct , console.log("Some text" / 2); // Output: NaN console.log("Some text" / 2 + 10); // Output: NaN console.log(Math.sqrt(-1)); // Output: NaN it is because nan is special value in Number datatype. suppose number is not valid then it show nan

[@asishkottakota3920]

Sir can u tell how to represent a single character

[@teluskosupport1]

let ch="s"; let ch1='s'; let ch2=`s`; just same as string
