Master Async JavaScript: What it is and How to Use it
Вставка
- Опубліковано 30 вер 2024
- Asynchronous JavaScript is one of the most important topics in web development. It allows you to write code that can run in the background without blocking the main thread. This means you can create faster, smoother and more responsive web apps. In this video, I will teach you the fundamentals of async JavaScript, such as callbacks, promises and async/await. You will learn how to handle asynchronous operations, deal with errors and write clean and readable code. By the end of this video, you will have a solid understanding of async JavaScript and how to use it in your projects.

Hello Sir You're providing awesome content Is react js Coming???? I don't wanna learn from any other course except urs So Please Reply
Yes, react will be here just after 100k mark
Full support hai bhaiya full suppot❤❤❤❤
Amazing content. Loving it❤. Please make more videos of such advance concepts if possible. Make it more detailed. I can keep listening even for 3 or 4 hours because your teaching style is that much amazing.
Waiting for React Js tutorial❤❤
[02:36] Introduction to Async JavaScript
[07:34] Synchronous code executes one after the other
[10:05] Understanding the sequence of asynchronous tasks.
[16:39] Asynchronous JavaScript allows for non-blocking code execution.
[19:39] Understanding asynchronous JavaScript
[28:22] Understanding the difference between synchronous and asynchronous code execution.
[33:31] Understanding event loop in JavaScript
[40:09] Understanding the behavior of setTimeout function
[43:20] JavaScript code execution and asynchronous behavior
[48:08] Promises can be in pending, resolved, or rejected states.
[49:53] Understanding the states of a promise
[56:36] Understanding promise creation and resolution process.
[59:01] Understanding the concept of promises and their states
[1:02:32] Understanding promises in async JavaScript
[1:05:04] Using async code and Promise to manage asynchronous JavaScript
[1:13:53] Understand the concept of third party dependencies and parallelism in JavaScript
[1:15:58] Throttling helps decrease the number of scroll event calls.
in a simpler term,
whenever the jsre discoveres any synchronous code, it will be executed first and whenever founds an asynchronous code, it will check about the priorities of asynchronous code, like if they are promises then they will be considered as a microtask which haves a higher priority to be executed as first, and the rest asynchronous codes like setTimeout() or setInterval() will be considered as a macrotask which haves least priority to be executed than microtasks, so whenever the microtasks executes, the macrotasks will come to the callstack and then will starts to be executed in synchronized manner!
pls. give a thumbs up for this biggest info in a short paragraph...
boht he level samjaya hai bhai kamal ka. teaching style superb hai boss. love from PAKISTAN♥
Sir, I haven't seen any teacher like you on UA-cam. Whenever I get stuck, your videos come to the rescue, and when I watch them, it feels like I've already learned the topic. You make amazing videos. Please continue this quality. People learn with ease and without stress. Love you, sir, from Pakistan, and thank you.❤❤❤❤❤❤....
Recently discovered your channel. You have the best JS content and the way you teach with such enthusiasm is just awesome! Can you make a JS DSA playlist?
Yes I agree Make DSA with JS
UA-cam bots commenting to each other lol
@@lordesca4364🤣😭
somehow mujhe bhi lagta hai k DSA course banana chahiye
Yes Please
Beautiful explained. It's a request to make in-depth videos on each async functions setTimeOut, fetch and more with real world use cases like a mini project. Loved the way you explained.
Swachch Bharat ko gaali mat do warna fir videsh jakar bharat ko hi gaali doge.. jese aap apna kaam kar rae hai wese wo safai karmchaari apna kaam kar rae hai...please mind it..and respect everyone... jis din kachra uthana band hogaya us hamari life kachra hojayegi...isliye cool banne ke chakka r me ksi ki disrespect mat karna .. You are great at ur teaching and skills and that is appreciable but respect all warna sab ek pal me khatam hojyegaa..coz KARMA IS A BITCH.
Teaching is never gonna be boring for the teachers like you... I mean it is enjoyable not because you use sl*ngs in between but for the simplistic way you explain and demonstrate all the concepts in which some of us might be having doubts.
love you sir I am from Pakistan. and I am proud to be your student sir❤❤
Your teaching on UA-cam is exceptional! The content you provide is top-notch and incredibly valuable. Your dedication to creating informative and engaging videos is truly commendable. I love how you effortlessly explain complex topics, making them easily understandable for learners of all levels. Your passion for teaching shines through in every video, and it's evident that you genuinely care about your audience's learning experience. Please create videos on React, as your contributions are immensely helpful to learners like me. Thank you for being such an inspiring and influential educator on UA-cam!

Usne bhi aisa promise Kiya tha but reject deke chali gayi #us_moment 😂😂😂
your main stack and side stack explaination was awesome❤
The video is great and also need more deep knowledge on ASYNC JAVASCRIPT kindly provide asap and also confirm by commenting me so that I can wait more
need more on axios, XMLHttpsRequest , setInterval, fetch and more.....
sir , next video on DOM
and your efforts are very great!!!
Wow sir...me bahut dino se sab creater ki video watch kari(code with harry love babber or bhi bhaut Udemy course liya learn Vern se js course watch kara simplilern bhi ) ..but sir jaise aapne desi langauge smajaya hai ... salute hai sir dil 🙏🙏🙏🙏🙏🙏❤️❤️❤️🙏🙏

Async and Await wouldn't have been this simple.....had i not watched this video. you are a "GEM" Harsh, keep doing the good work. Small Request......if you can provide some coding examples on Concurrency, Parallelism & Throttling it will be of great help. Thank you so much.
i saw one image pop up effect like pop corn. i am unable to it. how to achieve that effect. and i wanna tell you guys are doing fabulous job. bcz of you guys i am finding it really interesting to learn web dev. plz keep doing such good work. if you have added so many values to my life. once in life i wud really like to como to MP and meet you guys in person and thank you in person

Sir,
I need help with website responsiveness. My design and code are good, but the layout varies across browsers. Please share more videos on this topic. Thanks.❤
Yes, we are interested in watching related to Dom, and whatever concepts you have covered in this video, please make a project tutorial to understand the practical usage of those in real-life projects.

Outstanding content! This video simplified async/await in such an easy-to-understand manner. The examples and scenarios used were incredibly helpful. Thanks for enhancing my knowledge JavaScript .
Your teaching skills is very good i understand each and everything keep going brother one day You will buy a car for your Mom
I am a 43 years old female working in logistic and accounts, no codding background want to change the field in web development, learning speed is slow, but i found your way of teaching method is easy and relaxable for absolute beginners. ggod job thanks
Keep it up !
Congratulations for 200k already brother, just got laid off and preparing for interviews, you're videos are a gem 💎!! Thankyou for everything you do.❤
What a fabulous explanation sir 👏. Really thanks to you and your whole team for spreading this type of knowledge . Great job 👌
Brother your videos are amazing and i love them your videos gives the feel professional. yes you do a lot of talks but that's fine but brother please don't abuse in your videos that destroys that professional feel of your video i just wanted to say that. But after all thank you for making such amazing videos. Love from bareilly💝

Please explain the closure that you removed from this video to make a more application-oriented video around it.
sir love from Bangladesh. You are a totally great JS teacher . I shared your awesome channel with my programmer friends. We want a DSA playlist with Java Script . plz say my name in next video
7:41 background
35:30 brilliant example
43:30 async code bina handle kiye kyu nahi chal sakta
1:12:55 in that logic, in 3rd line, there should be another await before ans. Otherwise console.log will run before it gets the ans
33:35 best explanation for event loop ❤🙌
the way u guys teach is awesome , bole toh raapchik😃😃
I usually never comment on video's but this video is a pure gem because of you..i had a clearity in this topic,for anyone reading this please go for it..this video is the best thing to ever happen, i can't thank u enough ❤️
Bhaiya wo to queue na hoga stack ki jagah kyuki stack lifo operation perform karta hai yani ki last code call first 😢 to phir bottom code of stack pehle execute kaise hoga ?? Jaisa aap bta rhe hai 😢 33:28
Best coach ever I have first time complete all javascript series in a day because the way sir teaches id more like an friend rather than a teacher
Just a clear understanding ❤😊 great man..
Yes we want dom projects 😉 💯
Sir please js full course in 1 video
good job sir but more to go
and what about selecting by ids and inserting ,removing . we need that also
recently found your channel and I'm so happy to find this to learn JS from basics. I was born in Bhopal and I believe Bhopal has a diamond instructor like you. Thanks for creating such nice content.
right
us moment. usne bhi promise kia tha par reject karke chali gyi
No.1 way of teaching skill... No one can teach better than you.
I have a doubt?
jo side stack h usme saare asynchro code to ek saath chal rhe h na? ex - agr lets say C and D h side stack me c takes 2 sec and D takes 3 sec to dono C and D ek saath chal rhe h na side stack me ?
so how is it single thread?
Your teaching style is so engaging and clear that it's impossible not to learn from you. 💕
and mujhe to abhi pata chala when use promises and how to apply then and catch, also why to write async and await 😅😅
Awesome explanation 👏, like just wondering how you explained such a deep concepts in just a fun way. You're style of teaching is just out of the box 🔥🔥🔥
Thak God I see the promise in the other video but they make it complicated but you make it easier for me thank you bhaiya ❤
yaar internet par koeee b itnaa zayadaa acha or easily understandable nahii Perhaa rahha Love you Harsh Sharmaa from Lahore, Pakistan 😘😘😘😘😘

Async Js pe project chahiye jisme promise use ho raha hoga
bhai bhai bhai aap toh apne jaise ho ekdum bc aisa teacher sabko de bhagwaan
Full support sir ji..... Kya hi mast pdte ho aap.
We are the Same kind of Person Teach Us In your Pretty Style Sir,
CallBack : "38:05"
fetch , axios , promises, setTimeout , setInterval take time to give response and their response are handled by then-catch, asyn-await, callback
🙂
Awesome teaching skills. I want a 2nd and 3rd part of React JS as well. Ek Sharma ji ka dusre Sharma ji se Vinamra nivedan hai 🙏🙏
@harshsharma se padh liya to life jinga lala ✌✌
Your way of teaching just like a wow literally , I really liked the way you and sarthak Bhaiya made us understand that definition of synchronous and Asynchronous
Please keep teaching this way 🙏🤗
