Around 8:00 I said "videos". I meant to say "files". Everything is in this one video. I did not get to the libraries but we will do that in a separate video. Hope you guys enjoy!

[@saadmahbub8787]

[@priyaranjan1733]

Thanks a lot , Could you make some video for Javascript Flavours, like vanilla :P

[@ethashamuddinmohammed1255]

Try GoLang instead of NodeJS. You have a good thought process

[@FordExplorer-rm6ew]

How do we use ajax in production without CORS errors? Github pages? Heroku? Netlify? Which of these will work?

[@sanulankaraya9997]

Every time I hear that intro music, I feel really confident.

[@shivrajnag12]

It gives me similar vibes as Netflix

[@jesusgonzalez7059]

I know, right?! It makes me feel like everything is going to be okay.

[@yeahorightbro]

I disable adblock when I watch this channel. Brad, you're a hero.

[@TraversyMedia]

Thank you very much for that :)

[@braed6202]

I just whitelisted his channel too :)

[@gabgab841]

[@freedomfighter3686]

You mean you enabled adblock :) since disabling adblock means ads are free to come.

[@gjuteodoro6910]

Lol?

[@pedrosousa6576]

Woah how did you know I was looking for an Ajax tutorial?! I even watched your Json video yesterday and now you posted this. You're the man! Thanks brad

[@jamie10333]

This is one of the most straight forward tutorials I've watched for JavaScript. Most videos post either pure basics or pretty advanced tutorials. Been searching for a video like this. Thanks for this video.

[@vegasvato55]

I learned more with your videos in an hour than in all of the weekends of the past months.. I like the way you take the time to break things down and explain and diddle with the sections of code... The best i have ever seen... The way you play with things and break them is fantastic...

[@mynameis3005]

thank you for taking the time off to create such good content. you have inspired me to help share my knowledge in the future.

[@luciusrex]

@14:45 for those wondering, the fx open is inherited from the XMLHttpRequest constructor and can be found under the prototype (__proto__) property.

[@giddeo]

Really good, solid tutorial. I'm doing a course currently and this was just baffling to me at first but you've just made it so much more accessible and easy to understand. Excellent, thank you.

[@davza9629]

This is in my opinion the BEST video explaining AJAX on KZbin. I have scoured for hours and no other videos have explained the concept in such an understandable way. Thank you so so much. This is going to be so much help in Web dev classes at school. You, sir are a life saver.

[@iancarr3923]

These videos are invaluable. They serve as a great guide to html, css, ajax, etc particularly when reviewing videos from other providers

[@dustinhammack7024]

Thank you so much for this video Brad!! I have been struggling to understand AJAX, and this video just cleared up all the confusion I've had about it. I can't thank you enough!

[@rkireev]

Cant say thank you enough. Going through coding Bootcamp and I find your videos extremely helpful. Best on youtube for a fact. You are the man! Keep up the good work!

[@csiwele617]

Thanks again Brad, Your videos are a staple to my personal and professional journey as a programmer. Every hour spent on your videos is invaluable.

[@ajazmiah]

Can't explain how happy I was to see this pop up in my notification. Couldn't wait to come home and watch it as if it was a game I recorded while I was away! Lol. Great video 👍

[@TraversyMedia]

Thats awesome, I hope you liked it

[@shatterking215]

This really helped me learn the ins and outs of AJAX! It was also a nice refresher for php & MySQL. Thanks Brad!

[@saadwasil]

The most beneficial hour I've spent in the past few days. Thanks, Brad.

[@attilakatona2137]

[@TraversyMedia]

[@maskman4821]

[@dansintean6820]

[@ililiilili3366]

@@TraversyMedia hey, since i started front-end learning, i always wondered how do one ever connnect front end to back-end. I think i have a better idea now. i watched some parts but i understood. Will practice the content of this video later on. Thanks, dont erase it plz (LOL).

[@Jakhongir84]

Bard, you are the best man. This is exactly what i needed. Thanks for an amazing tutorials! Cant wait to go home and enjoy your content.

[@dhandayalprasad2267]

[@dunzek943]

Of course man, this is Brad Traversy you're talking about

[@LeeroyGgJenkins]

Thank you so much for not stopping at the simple stuff. I needed that last example for a project and I could not find an example anywhere!

[@danielioanitescu2134]

Brad, I wish you all the best, bud! You really are a teacher and your methods are nice, clean and easy to understand for all of us. Wish all the best for you and your family and keep it up with the good work. We need you 😁

[@mofe620]

Just finished this, right after watching the JSON Crash Course. Two hours ago, JSON and Ajax didn't just make sense to me (I had used them a number of times, without understanding anything 🤧). Right now, I totally understand everything. Thanks a lot Brad. You're amazing.

[@iWaxxy]

Thank you for the awesome videos, Brad. I haven't found a video that explains Ajax this well yet.

[@tigere01]

In just an hour, I now quite get the XHR object and the kind of situations where it is useful i.e. display data from a url without having to do a full page reload. Thanks a tonne Brad.

[@sahibrzayev8968]

Best AJAX explanation . Thanks a lot!

[@crackerdelicious]

Passed 4 Years, I still watching this. Love Brad.

[@renzycode]

For all ajax tutorials i've been watch, this is so precise and the best. Thank you Man

[@durgaprasadnagarkatte6470]

This tutorial is too good to learn the basics of making get and post requests with JavaScript. Thanks a lot.

[@matthewrossilini5808]

You're videos are so great for someone (me) who is just beginning to learn web dev (green as hell). You are so thorough in explaining everything, and you do it so clearly. Thank you!

[@danielk1560]

Thank you, This was my most well spent 1-2 hours in the last half a year!

[@simple_lide]

Thank you, Brad. Your tutorials are awesome. You actually do things from scratch, and explain every step. Also, I like those types of videos as - "been showed - now practice", short and valuable. Great! Wish you all the best from Ukraine! :)

[@shivamahlawat6702]

God level video....really was in need to get data out of a database without the page getting refreshed...A BIG THANKS!

[@brandonikjoo]

Thank you so much about the video. It's the best AJAX tutorial video I've ever have!

[@ladywebber1726]

You're such a great instructor. Thank you for teaching me a whole lot from your videos. :) very inspiring as well.

[@alexanderfrost1476]

This is the best JSON tutorial ive seen so far. So easy and straight to the point. I only stopped following at point 45mins because of the last examples using php. Still understood what he was doing because of the awesomeness of the earlier examples.

[@limitless1692]

This was the best ever Asynchronous javascript tutorial I ever watched . I finally understand how this Asynchronous instructions work . All that fog of confusion lifted up while watching and practicing your video . Really really really thank you very much Sir !

[@PeterJohnsonWales]

Love your stuff man! You've got a very lucid style. As a 60+ year old hobbyist Pascal & old type PHP coder, I'm finding making the leap to JavaScript tricky. You're really helping!! Thank you.

[@DanielBurchfield]

Great work through. I am an AJAX noob to be accurate, and this was a great way to get to know the tech. Much appreciated.

[@The-Average-Gamer]

Absolutely loved it! Would love to see more back end stuff

[@eemeelyo529]

This is QUALITY. I learn better in your video than in other online course. Thank you very much for doing this tutorial.

[@quachaihiep3251]

After few times coding and messing thing up , i finally got used to this request. Thank a ton, man

[@user-tm2qn6vk3v]

Extremely useful!! That's what i've been searching for. Thank you for the time spent on this lesson!

[@hematogen50g]

Thank you. It is very well structured tutorial. You are right about learning vanilla stuff first, it is so much easier to understand.

[@speakenglishwithjoe2023]

You have really made my day with this crash course. OMG very easy to understand. Thanks so much for this video.

[@dunzek943]

Brad hacks away (no pun intended) at the abstract and mysterious words, terms, and practices that surrounds programming, returning to us with mentally-digestible tutorials. Thanks Brad!

[@andresalvarez7303]

THANK YOU! It's so hard to find a good web dev tutorial nowadays that doesn't rely heavily on libraries (jQuery) or skips over many core concepts of how and WHY things work the way they do on the web.

[@Saleel4urHelp]

Thanks, Brad, For the well-explained video. Really loved how you explained each and everything so that even a beginner can catch up. Kudos

[@AkkayHT228]

Thank you! This is one of the best videos in YT about AJAX

[@drewconroy5938]

Great to see this video.I have been going to brush up on my JQuery for awhile now(from your tutorials) I think your jQuery tutorials with this tutorial back to back should do the trick. AJAX is one of those things I have always wanted to dig into deeper but never have. So, this will get me started...

[@agrajyadav9]

Great tutorial, looking forward to checking out your other vanilla javascript tutorials.

[@nicholasiloba5740]

Great Course. I used ES6 Syntax to follow along which helped with my overall understanding. Thanks Brad!

[@Kalerblind]

Among all the things I'm impressed by, the HD Audio and Video is the best i've seen in any tutorial videos :)
