Thanks a lot freeCodeCamp for posting my course. Really glad to give something back to this awesome community. I would really appreciate if you can support me at my channel as well: www.youtube.com/@DestinationFAANG
@DestinationFAANG need similar type of video for Queue
Working on it. Thanks @@rajaryan5884
@@DestinationFAANG I love the explanation, slow and easy to understand. Can you do more videos similar to this?
yes, you will see more videos like this soon. @@leozhong9270
I was searching for a dsa course just now..😂 Thank you fcc❤
Thank you so much for this video!
The best code camp for beginners... who all agree ?
it used to be simplistic... i like how overtime it has become more technical and theoretical information , the technology has become so high level and abstract.. that if u dont go to university... its really hard to learn from top to bottom... for me atleast... im currently implementing oauth2.0 SSO flow, and im sure im doing everything right, but have weird issue in Koa, using node-fetch , SSO resource owner , refuses, to send me aa json paiload back, like ... ;S says syntaxERror : Unexpected end of JSON input... im 100% sure that that fetch body payload is form urlencoded ;S im going crazy already, i ve asked few people, they all say i have written everything correctly, not a single AI model also thinks i have written something wrong.. ;s i even looked up some express examples of other people guides on implementi lets say oauth2 with google, i literally did it the same way as anyone else... does anyone know if node-fetch 3.3.2 is broken on windows platform or smt?... isnt unexpede end of json input like... if json is malformed? does windows and linux have different newline in http post request / response? im starting to think the sso service provider is ignoring oauth2 spec , im just getting either 500 , or a pending Promise ;s wanted to write it myself... i guess im going to just install some Grant lib/framework to do it... wasting too much time ; ] being stuck in such stupid problem... is discouraging... ;s
Let's get into this
Yeah let's go
Wow I love all his plushies!!! Fabulous! My office is the same
Can you do one for queues too please? 🙏
In process
He is needed in more FCC courses
👍
Hello, could you do a tutorial on creating a mobile app for handwriting text recognition?
Make path learning to full stack web dev, android dev (kotlin) ,iOS dev , mobile dev , etc , for all big categories.
Use chat gpt for that lol
@@killerdroid99 I don’t want use ChatGPT . They are best.
@@killerdroid99 I don’t want.

It would be more helpful if implementation of this is in Javascript
yep I agree
Free stack of cookies
using python will be best insted
First person who commented 😂
who would need this nowadays? especially with AI and today's spec.
Lol first
Last out
The accent is a barrier.
2.5 hours for stack!! You guys have no life, that is stupid!
another promosing tutorial ruined by Java...
