Loving this channel! Finally, someone explaining how things work actually and not just how to do it.

I am so loving this hooks series, it have learned so much from you. I am so glad to be part of your subs. 😊

Hi, that's a nice explanation! I'd recommend avoid using the ternary operator in the userType, as the `age < 18` and `country === "USA"` already return a boolean

[AAS-itko]

Great explanation. It's short, precise and to the point. Thanks.

Yes Safak,
It is a great idea to build a small project that revises the concepts in the last 4 videos.
We'll wait for that project :)

[baleastudy]

Those last videos you've made are priceless.

Another awesome video in the series! I've been creating my own code sanboxs for some of the tips you mention so that I can come back to them whenever I need them. Would recommend anyone learning from these videos to do the same to help concepts stick. 💪

Thanks,
Tom

I didn't quite get the Provider pattern. The basic rule of React re-rendering is whenever a state updates, the component as well as it's descendants re-render. But when we don't specify the children component and use {children} with provider, it's children don't re-render ?

Sir apki teaching style bhut acchi hai..aap angular ke video bhi Lao na please

[reiito]

Great video brother. Do you have advice on using socket correctly too ?

[guyefrat]

thank u for another knowledge, so much inspiration

[msalameh]

Many thanks Safak bro, excellent as usual, but you become very fast with using tabnine, i used to follow when u are writing and seeing, now i have to stop the video several times and reward to see the written functions. I know it makes writing easier but for learners becomes difficult to track, anyway thanks for sharing, you are the best.
