I'm usually not using custom-hooks because I lack the imagination where to use them, and video just gave me 2 great ideas, thanks ! :) It would be great if you could do more videos regarding different common custom-hooks like these ones.
Yup, I think we don't have the coders' minds YET!!! or maybe we need to throw ourselves into the fire of a working environment to get creative and find use cases of various programming concepts.
It's worth taking note that the views counts for this series dropped from 216,154 views (1st video) to 42,597 views (last video), maybe means there 's a learning curve; and I am proud that I watched all and code along. Great work Kyle!!!
Great series. You really helped me figure out the difference between the different types of react hooks. I was not having the easiest time trying to figure it out looking through other people's code. Thanks man. Keep the videos coming. You're great at what you do!
React and hooks are so freaking fun. I just got my first job as dev and first task was creating a frontend all with hooks, apollo graphql, typescrypt and redux. When you figure it out you can play around with data really nicely. PS great channel
useLocalStorage hook should be implemented in React by default, it makes the operations on local storage so clean i can't imagine doing it the "default" way again. Thanks for another great tutorial! :)
Thanks for the great series on react hooks. Will definitely have to go through it a 2nd time to let all the details sink in. But I have good overview of it now.
This example is perfect for me! I was creating a React project to manage Arkham Horror LCG stuff, and just had to saved in a big ol state. But for saving games serverlessly, local storage was gonna be the way I handled it. This idea will meld in nicely with saving my data, woot!
Before knowing this...I also use to the same thing....saving things in local storage....today he made this a react custom hook Kyle do knows how to use his tools appropriately and in efficient way
Thanks for the good video! But I think your useTimeout function should be like something like below. export function useTimeOut(callback, delay, dependency) { const callbackRef = useRef(); const timeOutRef = useRef(); useEffect(() => { console.log('callback update'); callbackRef.current = callback; }, [...dependency]); ... } because like you mentioned, callback without 'useCallback' is different always.
Now, why not to bring this to another level? build your custom hook useStateStore, then create useReducer inside, import store hook into your components and voila, you have global store like Redux. Also, you can privide that store using context api... :)
Can someone explain what he does starting 5:02? "And now we what we can do is use a function version...". As opposed to what? Does writing an explicit return statement make it a "function version"?
Can someone please explain: why assign a function in useState will reduce the call of localstorage, like he said in 5:20, "only call this once when first time rendering the component, not everytime render". I mean this function in useState still returns the result of function savedValue, so why not write like const [value, setValue] = useState(savedValue(key, initialValue)) ? Can anyone explain it?
I don't know if you already found your answer, but just in case... When using a function as initial value for useState, we need to practice "CURRYING" or wrapping function executions in another function, like this: useState(( ) => someFunc( )) as opposed to just: useState(someFunc( )). This way, someFunc doesn't get called unnecessarily every re-render. It's not noticeable on small apps but treat it as an optimization with the way useState hook works. In the video, the data from local storage is only read at the initial component render. EDIT: Try putting a console.log( ) on the function and compare. The one with no currying will show the log every keystroke.
actually i tried the same code with a signle function , in the same component, and it works fine, but i cant use useEffect inside a function,for that i just made a if check, and if we want to use a useEffect inside a function, that must be a react component, or a custom hook, that is fine, but here the important thing is with a custom hook we can use it several times, instead of writing the code again and again, thanks for the awesome video,
Is "if(initialValue instanceof Function) return initialValue();" necessary? Because if using a console.log() to print out whether it's true or false, we'd always get "false". So, what's the reason to use this line of code?
Really, really awesome video!! as always by the way I wanted to ask that can we make android apps in like plain javascript without using React Native and can we use js with C++ or python?Thanks!!
Android supports c++ natively and has its own NDK but why you'd want to mix it with js im not sure. PWA is basically using js and c++ just the c++ is written by the browser vendor. Its all possible but the practicality of it will depend on the kind of software you want to write.
@@fredhair hey there!! actually, I was thinking that it would be easier to make a user interface if we combine c++ with js, HTML, AND CSS maybe Node js would do it.
Why on the useEffect does React complain about ' key ' being a missing dependency? I've seen this in a couple tutorials now, has something changed with React?
great video, but I don't get why the input wouldn't be persisted in the first place. Isn't the value of the input field the useState "name," whose value would persist through refreshes? So after you type something in and set the useState to that input, after a re-render why wouldn't the input just reset it value to the useState value that's still there? Thanks a ton
Kyle, how do you get the localstorage in chrome to update when the state is changing? I had to refresh the localstorage to see the new value. Can you please help?
In getSavedValue function: "if (savedValue) return savedValue" What if savedValue is false or 0 or an empty string? Shouldn't it be like: "if (savedValue !== null) return savedValue" or am i mistaken?
damm, i am hooked now
get out
what are yuo 14?
I see what you did there
Ahhhaha I love the pun😂
I like how you react to this vid

You have the best tutorials. You never add a bunch of unnecessary commentary and for that I thank you.
i have finished all this react hook series in this channel, literally worth every seconds. Thanks Kyle
You're really simplifying the web for me
this video is so underrated, it should have like a billion likes. thank you

The way you explain it, i am in awe of it.
you are one of the best that explains, thanks a lot for all the useful information
Great series. You really helped me figure out the difference between the different types of react hooks. I was not having the easiest time trying to figure it out looking through other people's code. Thanks man. Keep the videos coming. You're great at what you do!
Wow man. You really have made the web simplified for us to build our project. Awesome content as always👏

Id love to have that kida job
Please keep this up this is really great. I just finished your entire hooks Playlist. Thank you😊
Thanks so much for these videos, they are very concise and easy to follow.
Your video's is awesome. It's so simple to understand what you are saying! Thank you so much!
Thanks Kyle... These videos are really helpful for beginners.
Thanks for simplifying react for us!
i use redux toolkit and it helps me a lot. but really thanks for the video. we love u
Thanks a lot for this video. learnt something new today :)

I am "hooked" to this channel..
TH-cam should make a two like button only for your channel because I would give you two likes
i have three letters for this video WTF ---- hands-down best explanation of custom hooks... thanks Kyle.
Thank you! This is very much simplified to me!
Great tutorial! Thank you for the explanation! 💛
best explanation ever!! thank you
Superb kyle, every thing is clear
Greatly explained the concept!

Awesome explanation, genius guy
really great tut. thanks dude
thx already shared to Twitter
liked it, loved it, just the thing I was looking for. Thanks very much.
Thanks for this great tutorial.
amazing, thanks
great tutorial series, thank you so much
nice bro thanks for giving this video
Thank you very much! great video
very nicely explained
awesome learnt about local storage and hooks
Great little video, as usual, Kyle.
This is awesome, thanks so much.
Thank you
Amazing video. I'm in love with you!
Great explanation kyle ..please make on one video Event loop
Thanks a lot for the video.
Good job man!
thanks!
Before knowing this...I also use to the same thing....saving things in local storage....today he made this a react custom hook
Kyle do knows how to use his tools appropriately and in efficient way
Awesome, thank you
You can even add a deleteItem function inside useLocalStorage to delete the item if the user needs to
Wow thanks
Imagine getting hearted by one of the best teachers on the internet
thanks, sir for such awesome video, if you possible please make some videos on react recoil.
One question, why will initialValue be a function?
This is great!
Great ✨
Great, thank you :)
I ate these fucking hooks bcz of you, the great Kyle
This was a great example... However if this example would help to stay login in after refreshing ..would be great
te quiero mucho, gracias
It just works!
Mind blow video
Thanks for the good video!
But I think your useTimeout function should be like something like below.
export function useTimeOut(callback, delay, dependency) {
const callbackRef = useRef();
const timeOutRef = useRef();
useEffect(() => {
console.log('callback update');
callbackRef.current = callback;
}, [...dependency]);
...
}
because like you mentioned, callback without 'useCallback' is different always.
Awesome!
Hey, thanks again for another video! Can you make on related to wherr to store jwt on the client side?
Even though how simple the last hook was it can be pretty handy in debugging stuff
Hey Rohin
Have you been working on any react projects currently? Are you open to internship/job opportunities in software development ?
Can some1 explain to me why using a function in useState can help reduce the call on localstorage ?😊
Hi Kyle please make a video on Instant search filter like youtube on react.
god damn good tho full skilled in this shit :D thx for ur video
so custom hooks combination of function and component we take argument and return / without return . also we can useEffect within it .
how can initialvalue be a function. i didn't get that part. can anyone explain please
You are the best
I am waiting for the MERN video ! :)
this would definitely be helpful in react native
😀

ty.
just a little improvement, for the the custom hook we can use named-parameters, in that way the order of the parameters does not matter.

I mean this function in useState still returns the result of function savedValue, so why not write like const [value, setValue] = useState(savedValue(key, initialValue)) ? Can anyone explain it?

Hi Kyle, I really like your videos and the quality of the image. What camera are you using? Thanks!
It is a logitech brio shooting in 1080p
@@WebDevSimplified Thanks a lot!
Hey, a question, does a hook persist and share the state through multiple component, like context-provider works?
Is "if(initialValue instanceof Function) return initialValue();" necessary? Because if using a console.log() to print out whether it's true or false, we'd always get "false". So, what's the reason to use this line of code?
Dude how are you making your hair like that every day :D

Really, really awesome video!! as always by the way I wanted to ask that can we make android apps in like plain javascript without using React Native and can we use js with C++ or python?Thanks!!
I know one way to use js with python is "eel" but not don't know about C++ with js.
Android supports c++ natively and has its own NDK but why you'd want to mix it with js im not sure. PWA is basically using js and c++ just the c++ is written by the browser vendor. Its all possible but the practicality of it will depend on the kind of software you want to write.
@@fredhair hey there!! actually, I was thinking that it would be easier to make a user interface if we combine c++ with js, HTML, AND CSS maybe Node js would do it.
I don't get why "useUpdateLogger" needs to use useEffect at all? Since it's prop/input parameter is constantly changing, why do you need useEffect?
can you please create one more video , where we imlpement fetch web api in a cusom hook?
Do you have a course with Hooks + Redux ?
Why on the useEffect does React complain about ' key ' being a missing dependency? I've seen this in a couple tutorials now, has something changed with React?

Because a rerender is not the same as a reload
Sir Please make a tutorial on useSelector and useDispatch hooks
useDispatch is basically mapDispatchToProps and useSelector is mapStateToProps.
Good
Kyle, how do you get the localstorage in chrome to update when the state is changing? I had to refresh the localstorage to see the new value. Can you please help?
