Why set state for the search term? You can just set filtered fruits state in handle input function and filter using the event target value.

[foysalmohammad]

Good video with nice explanation.
I think two states are not necessary. You can Just use one useState variable to store onchange value of input element, and then filter
like this: const filteredFruits = fruits.filter((fruit) =>

);
And render filteredFruits

[akhilkumarsingh]

The third Qs can be solve like this as well!! am I correct


import React from 'react'
import { useState } from 'react'
const PhoneNum = () => {
const [phone, setphone] = useState("");
const handleInputChange=(e:any)=>{
let value = e.target.value;
let numericValue = value.replace(/[^0-9]/g, "");

if (numericValue.length > 3) {
numericValue = `(${numericValue.slice(0,
}

setphone(numericValue);
}
return (
<>
<div>PhoneNum</div>
<input type="text" placeholder='Type here' value={phone}
</>
)
}

export default PhoneNum

why do we need to create fruitData state in question 1? Can't we just filter the original fruits array based on the search term state? Eveytime the user types in a new search term the component will rerender and this refilter the data - doesn't seem like we need the additional state for the fruit

[naveenbasyal]

1st and 2nd is pretty nice and easy, which we use on daily basis but the 3rd one is definitely the trickiest one, although we mostly use libraries for this but it's better to understand how things are working, we'll surely gonna forget the logic in future even if we try to do it from scratch .

[juancarlosrodriguez]

Hello Pedro. Your videos are very instructive. I’ve learn a lot with them. I would like to ask you for a video where you implement & explain the search functionality in a MERN scenario with redux toolkit for state. Thanks a million for your hard work.

[deadbt]

Thx for sharing this knowledge with us Pedro!

[Misica]

Second task is much more complicated with that useeffect shit, why, just why programing couldnt be simplier?...These are examples why people quit

[viveksah]

This is pathetic it’s showings you don’t have the basic understanding of react it can be done only one function by useing useMemo with filter why do you need so many use effects and const
