I am thrilled to share my knowledge here with this crash course. Looking into the positive responses even after a week of publishing is very motivating. I will make more such and share them with the larger developer community. Keep learning, my friends. 🤝

[Youarenotme]

Many hindrances have been solved by only watching a flawless video created via a professional teacher . thank you sir

[ajalajessica]

I just started learning JavaScript… this is far better than the bootcamp I paid for

[ichiroutakashima]

tapasadhikary's "How to take this course?" is basically the most important aspect of this video that can apply for most tutorials out there. you really can't consume content in one sitting and it shouldn't be a shame to repeat the topics and rewatch them. Don't move on unless you feel you have a full grasp.

[adarshagnihotri]

Thank you, sir, for generously sharing your knowledge about JS functions. Your clear and thorough explanations have resolved many of my doubts.🙏

🪄I'm in super fast paced JS course rn /it gave us identical content in 4 hours/ I was lost no one else in the class will ask questions- so frustrating. I coded along with VSC and took pauses and back skips= life is better!/ SUCH a thoughtful and WONDERFUL teacher! THANK YOU! I will definitely be back 🔮🪄

[ejikeaneke]

It is wonderful to even major on this topics function. This will help a lots of new developers. I know how long it takes me to understand function, had it been that i saw this video earlier, my life would have been better with out stress. Thank you sir for this video and God bless you.

[dsouzaedson]

This was an awesome video. Tapas way of explaining the concept using simple example is very effective. Thank you for creating this course.

[ncgcogv]

you are explaining the things very well but is it possible to make this kind of video about functions with real logical operations where you show us how the functions work with real jogic instead of a, b or x, y etc Thanks in advance!

[fukkoff]

I cannot emphasize how jedi your teaching style is. You make inconveniently misunderstood, simple/complex concepts conveniently understood.

[soumadip_skyy_banerjee]

Y'all doing some VoodOo reading our minds!
