This one is important for JS developers.

For getting total number of arguments, in ES6 we can do let x = function (...args) { return args.length; } and for the method chaining we can use return this;

Brother you are one of the most efficient teachers for teaching programming on youtube that i could find.You explain concepts really well.Its sad that youtube is doing this to constructive youtubers like you.You have all my support!

"This is an INTERVIEW, not a RACE" -techsith ☝️

This question with "returning total number of arguments" can be solved in much simpler way. const x = function(){ return arguments.length; } The object 'arguments' has property ''length'.

This is great, I have a couple of job interviews next week for JavaScript roles and you have really helped me to build my confidence in preparation for this. Please keep posting videos :-)

5 years later and this video is still relevant. I didn’t watch it fully this time… but I do remember everything about it vividly. An absolute classic❤

I am following you since couple of months.. You are champ man. Keep it up.. 1000 likes from my side

To print the length of arguments (17:33), we can simply write: return arguments.length; inside the function instead of using Slice method.

Very interesting JavaScript question! Thank you for sharing!! Thank you for taking time and effort to make so many nice JavaScript videos!

Your all videos so far I have been seen are really deserves thumbs up ( 👍 ), Please keep doing your good work... and hope KZfaq should not harm you.

KZfaq's algorithm is so stupid. Your videos are good quality and don't deserve to be demonitized.

I've been watching your videos over the past few days and they've been extremely helpful and informative!

Love those tricky questions, we actually keep learning :)

You helped me a lot in job interviews. Actually I am preparing for an interview right now with the help of your video. Thank you!

What a fantastic videos. I remember watching your one year ago it feel like nostalgia, because i spend hours and hours watching your videos, trying to understand things. For now, i did not find better one tutorials on JS stuff on youtube at least. Just fantastic.

Getting ready for my first interview, your content is really helpful

I learned new things. Thank you clearing my Concept 😇

Thanks for making this video which helps me understand tricky concepts of JavaScript. Thanks a bunch

This is one of the best channel to advance your JavaScript.

There is no inappropriate content in this video, dear KZfaq

Thanks for tricky question - didn't aware of this magic

6:10 That's a cool trick to impress your co-workers, If they dont know it 😂😂

@3:26 now I fully understand how styled components work. You are such a good teacher

Best Interview series!

Please keep up the awesomeness.

@17.25, a more concise solution is: const x = (...rest) => rest.length; Awesome video, Techsith. I'm 100% subbed 🏆🎊. Most of these questions really had be thinking haha

Thank you for helping strangers! I hope KZfaq does right by you and you can keep the videos coming. They're a great help.

I love ur videos, thx!!!

Awesome tutorials man.

Thanks for your work. console.log(arguments.length); vs console.log([].slice.call(arguments).length);

I'm finding all your interview videos helpful. I have my first ever on Monday and feel much more confident going in.

my first javascript interview coming up very soon

Nice video, keep up the good work! (:

The reason you cited why the interviewer asks such weird questions are all very correct.

This video is important video for ui developers. Very informative video infact.

Great interview questions 👍🏻

Thanks! Great video! Hope KZfaq will change its policy, keep it up please)

your videos are awesome and KZfaq is very discouraging. Keep up the good work sir.

seriously very much needed video for developers

Amazing! The String constructor one was cool haha

Appreciate & yes maximum people make a list of questions to ask from the internet for the interviews & then start expecting the answers for those questions from candidates & in reality maximum interviewers also dont have any freaking idea for those answers. But current interviews have become a race, a questions/answers session, a Viva.

Thanks for the video. We all support you for all the hard work you are doing!

What a great video. I had my hand over my head all the way. Like I would literally fail all the questions without your solutions. Thank you so much.

This is very helpful. I am conducting JavaScript interviews in the next couple weeks. This has been a great resource (along with your other videos).

Thank you so much for this. It's interesting to hear your perspective on these tricky questions and I appreciate your openness and honesty about youtube monetization

I’m just here to tell youtube this video is important!!

Thanks for making this video. Its a great help for guys like us.

Super helpful video while Im studying for a job interview

I did not know about the contenteditable attribute!! It's awesome

Nice tricky questions. These are proper genuine content videos.

function a() { console.log(arguments.length); } Above will also work for arguments length.

Thank you. I have my interview tomorrow and if I pass it, it thanks to you.

Techsith videos have been very useful to me. Thank you.

This was a very informative video. Thank you for creating it! I'll be sharing this with some of my programmer friends :)

this video is important for JavaScript developers !!

u have gr8 knowledge on Javascript. I am learning a lot from u. I am looking forward for more technical videos from u.

you are great at teaching. very useful examples to understand js

I am already subscribed to your channel and I get alerts but I wanted to let you know that I really appreciate your content thank you for making videos and posting them for us!

5 years later still a great content ✨

I'm studying my interview with your videos. If I pass, I will edit my comment and I hope it's going to be well because the videos are very great. The contents are preparing the audience to the tricky and hard questions. Especially the ones that include mock interviews. Keep it going!

I'm grateful for all the effort you are putting in which makes learning so much easier. Thanks for all the hardwork

Very informative video . it's really help me. Thank You Sir

Grear video! Always putting out worthwhile content😁

'Document.body.cotentEditable = "true" ' is super cool !!!

Really helpful video! We need more of those on KZfaq!

really helpful for learning strange things about javascript.

Hi Sir, Your javascript interview part of videos are very helpful. actually I have found an another way in that question of function return total number arguments you have explained like function x(){ return [].slice.call(argunments).length; } x(1,2) // 2 length Found another way is arguments is a array like object it has number of array of arguments of function function x(){ return arguments.length; } x(1,2,3) // 3 simply we return arguments.length that will give lenght of arguments of function am getting answer for this way too.. Thanks once again sir.

Very interesting JavaScript question! Thank you for sharing!!

All the videos are career-boosting!!!

The way you explain the JavaScript are really awesome.

Excellent video!, I didn't knew about content editable property until now. Thanks!

Thank you so much for this video! I hope this channel grows even larger!

Best KZfaq channel for JavaScript interview

I am a new subscriber, and I can tell you that I love your content and videos... It is awesome!!! keep up the great work :)

Very nice and useful one. Techsith really helping the community...

By far the best channel for learners!

Dude I love the videos you're really helping me and many others on our Dev path

question : function return total number of arguments. // do not use loops. let x = function(){ return [].slice.call(arguments).length; } Below one is more simple : let x = function(){ return arguments.length; }

This video is great but and your explanation is good. I really did't understand the concept of asking these kind of questions in interview. Until and unless you faced these kind of scenarios in real time you never know the answer. I do have some decent experience like 6+ in JS but I faced these situations very rare when we work on framework. (9 out of 10 developers dont remember things after fixing an issue) So if some one answered these kind of questions means they saw these videos(assume {some number} out of 10) or read somewhere. So what are you interviewing real time experience or some interview preparation ? As an interviewer I will ask concepts(not these tongue twisters). architecture of application/framework and mainly approach on solving problem and wiling to learn.

your videos are so important for any developer.

im glad you fixe YT problems for ads...your videos eally helpme a lot thanks👏

Thanks for your videos, they are always so helpful. Learned some great things from this one !!

Thanks for this video, and thanks youtube for not blocking it :-)

Please come up with more videos of this type. It would be very helpful for interviews. Thanks

You're awesome, your videos are helping me a lot. If I pass my interview tomorrow I'll become a patreon. Thank you very much!

Thank you for taking the time to teach us! Cheers

Hi, For simplicity of typing I have used iife... Why you have done like this ? any benefit? (function x (a , b, c, d) { return [].slice.call(arguments).length; })(1, 2, 3, 4); Instead of simply returning length of arguments array like- (function y (a , b, c, d) { return arguments.length; })(1, 2, 3, 4); Thanks, Rahul

found tutorial very useful. Learnt new things in JS. Thank you.
