Thank you for explaining the "Why we use it". This often isn't explained and it definitely helps with understanding. Well done!
Thanks so much for this.
Currently learning Javascript on Codecademy and was hell of confused at the "HIGHER-ORDER FUNCTIONS
, Functions as Parameters" section, but this clarified everything. I'm so grateful.
I've previously favoured interactive learning of CodeCademy and FreeCodeCamp, but you've made me now look at video tutorials in a new light
Great example of callback, your calc function and callback really shows the reason for using callbacks.
Most valuable 15 mins of my day. Thanks! (y)
This is exactly what I needed to understand how callbacks work. I'm doing a node tutorial that has anonymous callbacks defined in-line and i had no idea why you would go out of your way to make a function more complicated by writing a function around it. This clears it up SO much
This is the best description of callback functions I've seen in all the internet. ...and believe me I've searched far and wide. Thanks for breaking this down for us!
been scratching my head trying to understand callbacks in java. thank you very much for such a nice relief!
Best explanation I have found yet. You made callbacks very simple to understand. Thanks!
Thank you, thank you, thank you.....I thought i'd never understand "callback" function, I've watched a few videos on this subject and could not grasp it and nearly gave up........but now......Thank you again.
Thanks for watching!
Have spent days trying to understand the "callback", finally got it after watching your video. A huge, huge thank!
Amazing, I had 3 hours of this on my class yesterday, couldn't understand a thing! Cristal clear after 15 mins of your tutorial, thanks a lot!
You're a hero! Thanks for this great tutorial!
Hey, thanks for this, it's a very easy to understand explanation, I appreciate it!
The only one to come up with a simple and straightforward example of callback functions. Thanks!
Making it straight to the point. No BS.
Now I'm confident in using callbacks eventually forever. Thank you.
Thanks for watching Sridhar. I am glad that you will remember this forever, my job is done here. :)
Thank you! Finally a well explained video about callback functions. It's hard to find nowadays.
Thanks for such an excellent video on callbacks. I've read a lot and been through a few videos trying to grasp callbacks and it hasn't clicked in my head until I came across your video.
This is the first video anyone and everyone should watch on this.
So many videos go SO deep and complex without covering the basics that its almost impossible to learn.
But you my friend.
Are the best.
Thanks Rick for the nice comment
This was a simple and clear explanation! I finally understand callback functions. Thanks for making this!!
Thanks man! This tutorial made me understand callback functions. Great way to explain essence of this JavaScript part :)
I've been struggling for many hours finally understand callbacks. Thanks sir.
after 3 hrs tried to figure out callback function, I found this video and help me understand how and why to use callback. thank you Sir.
I love the way you correct the syntax errors but leave the word back spelled incorrectly. That's a true programmer haha
finally a great explanation with the WHY aspect!. Thank you Sir.!
I have been trying to understand callbacks all day on various blogs and other videos and this is the first time it is making a lot of sense. Great video and explanation.
Glad you got it. Thanks for watching
Helped me big time! Thanks for this!
Extremely good teaching. Argument caught, no error thrown.
Thanks :)
You're the best! I spent two nights trying to grasp this callback concept and ended up understanding little. You made my progress real. thick books aren't always good :(
Whenever I'm about to watch your video I know that by the end of it I'll understand the concept I couldn't wrap my head around.
Thank you, kind sir!
PS. Thanks for taking time to brush up on your accent. Normally it's quite difficult to understand everything when the speaker has a strong accent. Have a nice day, kind sir!
You actually teach these concepts very well. My bootcamp does a horrible job of explaining these functional programming concepts.
Out of all of the videos on youtube, it's this one that gave me the eureka moment. I was very familiar with using callback functions in this way: someVar.addEventListener('click', () => {callback}) but creating a callback as a parameter for another named function really threw me off. Reall well explained. Thanks dude!
well explained!!! this tutorial clear talks about callback function!!!
just want to say it has been well delivered and well prepared.
Thanks ! Thanks for this simple and well explaining video!good job..
Really u have explained very simply & smart way that anyone can catch it clearly and easily. Great job. Carry on and good luck for the next tutorials ;)
NOT ANYONE , I am the type person that does not understand ABSTRACT information and then can be expected to apply it to a real world situation. I have no idea what he was talking about and I have watch SO MANY JS videos I cant even count them. I understand HTML, CSS, PHP, SQL but I have yet to see a JS video where they apply it in a real world scenario all of this abstract language means nothing to me. ALTHOUGH, I am happy for you that it all makes sense. I just wish I could find a video that would TEACH JS in actual usage and not in abstract techno information.
Good job dude. Thanks so much for making things look simple and easy to understand!
Great example of callback. Thanks man! This tutorial made me understand callback functions. Finally
a well explained video about callback functions. It's hard to find nowadays.

You are really awesome. I just love the way you explain complex concepts.

I am studying a course in JavaScript and they explained (call back function) but I was so confused after I was done, they made it seem so hard. Thank you for explaining, great JOB.
i have been following your tutorials from some time and really wanted say thank you for ths wonderful job. not all got the capability to make others understand in a simple and precise way. again thank you
Hi there! your videos are very easy to understand and are all briefly explained, thankyou for making these videos! also I think it would be useful for you to create videos talking about the classes, constructors, and extending them in es6 because they seem to be also something which is going to be helpful at times. :)
I am going to create a tutorial on classes next.
this is the best video so far i watched
great example. understood . thx
Thanks for depicting everything so clearly. Helps me understand callbacks a lot
You are doing a great job. Thank you.

Thank you very much. Perfect tutorials..

Thank you so much! I learn a lot. I see that you are not uploading videos, you must return and teach the next generation. You are a great teacher!
“just in case somebody pass a garbage”
😂😂😂
:)
@@Techsithtube hhhh you are funny as hell you and i really enjoy your tutorials
let garbage = function(trash) => {...};
my favorite statement in the video
Thanks for the video, one of the easiest to follow out there. Thanks again!
I'm a java developer with 5 years of experience in the technology and peripheral frameworks. I've recently started to mug into JS as our new requirements are all transitioning into it. As you can understand it's a new territory and the all these functions acting weirdly is mind numbing for a java guy. Thanks so much, your video helped me so much in understanding the core need for callbacks. Please make one on promises.
really enjoy your vids. thanks, so much, for making them!
The clearest description ever :) thank u!
Thanks for watching! :)
Best explanation I've come across! Thank you
I really like the way to teach stuff, its comprehensive and clear, thanks for taking time to make these videos.
Excellent explanation. Thank you.
great Job bro!!!!!!!
Thanks techsith! This definitely cleared up what it means to callback a function. Sir, You are AWESOME!
You are most welcome! When started learning JavaScript, callback function was so confusing. Once you know callbacks lot of thinks openup
Nice, simple and to the point. Thanks!
