finally mein 80 video tk pahuch gaya .. beech me 8-10 din bhatak gaya tha but ab nhi .... ab to pura ker ke hi dum lunga ...thanku harry bhaiya💌💌

[Codewitharu]

Lage raho harry bhai you are greatest person for all poor students❤❤❤❤

People who studied Java from him laughing 😂😂😂 when he is saying oops is just only this😂😂😂

[muskanmalik-kphj]

sir ji jo student payed course nhi kharid skte ap unke liye vardaan ho❤

[hashirraisani]

harry bhia you should change the thumbnails according to the languages like yellow for js red html blue for css and so on.. and pin this comment bro❤

[ptlunknown]

Sir, your notes are very helpful but sometime I need to read something for some reason I had to find it from 80 pages it take so time

[RamDas-cfsb]

The best thing about him is that he finishes what he starts

Not like some other people who just drop ongoing series just because less view

He makes quantity content with his whole heart and really cares about us and wants to teach as good skills ❤
Love your videos ❤😊

[AliHaider-trrm]

#problem Harry Bhai please make good consistency and upload daily videos🥰🥰

14:25 मेने अगली वीडियो में भी लिखा था, एक और प्लेलिस्ट में आपने javascript मे सब कुछ include कर दिया है, तो फिर से web developement मे इतना डीप जाने की जरूरत नही थी, क्यू की जावा प्रोग्रामिंग अलग चीज है और वेब डेवलोपिंग।जैसे की आपने भी कहा क्यू कोड कॉम्प्लिकेट किया जाए अननेसरी।जानने की जरूरत हो इतना रखते तो ठीक होता, हालाकि लर्नर के लिए तो अच्छा है ।लेकिन आपने already यही नोट पर सब फंक्शन और एक्सरसाइज अलग प्लेलिस्ट में की ही है तो इसमें फिर से पूरा जावा लेने से कोर्स लंबा हो गया।इसे भी एक कोर्स था ही html, css, js का।

[garimamishra]

Sir please make sort vedio on its solution. I can't find solution any where That can satisfy

[nikhilchouhan]

Harry bhai freshers ko front end me first job ke liye kitna js ka knowledge hona chahiye, uske liye 1 video banao, or job lene ke liye best platform bhi batao

[OnlyEducation]

It's very useful tutorial than u sir

[UbaidKhan-liyp]

Salam ...
A lot of of love from pakistan bro ❤❤❤❤

[fohadansari]

Sir how many lectures remain in Sigma web developer

[garimamishra]

Hey guys, I have a question about c language.
Why c compiler returns in output a large negative number . If u also face this problem and u don't know why? Then react this chat.
