I apologize if my voice sounds strained. I had to record this video 3 separate times because it wouldn't turn out right. My voice REALLY hurts 😂


import ToDoList from './ToDoList.jsx';

function App() {

return (<ToDoList />)
}

export default App

import React, { useState } from 'react'

function ToDoList(){

const [tasks, setTasks] = useState([]);
const [newTask, setNewTask] = useState("");

function handleInputChange(event){

}

function addTask(){
if(newTask.trim() !== ""){
setTasks(t => [...t, newTask]);
setNewTask("");
}
}

function deleteTask(index){
const updatedTasks = tasks.filter((_, i) => i !== index);
setTasks(updatedTasks);
}

function moveTaskUp(index){

if(index > 0){
const updatedTasks = [...tasks];
[updatedTasks[index], updatedTasks[index - 1]] =
[updatedTasks[index - 1], updatedTasks[index]];
setTasks(updatedTasks);
}
}

function moveTaskDown(index){

if(index < tasks.length - 1){
const updatedTasks = [...tasks];
[updatedTasks[index], updatedTasks[index + 1]] =
[updatedTasks[index + 1], updatedTasks[index]];
setTasks(updatedTasks);
}
}

I’m not a react beginner but experienced dev who just wanted to go back to good old times and watch some beginner tutorial and I truly loved and enjoyed this video. First time seeing your video and it’s absolutely nice and well explained. Keep up the good work and to the guys who are watching and maybe just starting - don’t give up, study hard and see you at the top!❤️❤️❤️

One of the best tutorials on how to do a todolist in react.

[michaelschroeder]

I just watched your entire react course this far and it have been a life saver thank you! You taught me Java, C, HTML, CSS, JS and Python, literally helped carry me through my degree.

[abrahamsimonramirez]

Petition for a Svelte course, I am starting to watch a 20 hour long one, since svelte is less troublesome than react it could be possible to have a comprehensive course in maybe 5-8 hours plus I like your style. I will anyways check documentation when I get some time to spare. No pressure though just an idea you'll perhaps like, ❤

[hasnainmalik]

Please never stop making this kind of useful video...❤

[greengoatsht]

Hoping that you will upload more videos in react js. I've been watching your videos from HTML, CSS, JS and this react js tutorial your videos are very understandable. I hope this coming 2024 I will be a frontend developer as a stepping stones into full stack developer.

Quick and clean but it take time to understand the logic how the up and down function work

[shaikshahed]

The best todo list app teaching on youtube by React

[danielo_tunes]

Thanks bro, very helful for my first react app

[mediasmithsllc]

Awesome video. One of the easier ones to follow that made sense and was short and to the point.
How would you include an option to edit an item on the list?
(Thanks again and keep up the great work)

[rohannaidu]

I just logged in to Youtube to tell you thank you for this.

[deeplife]

Hey bro. So happy to see you back in making video on but please make video for Springboot too

[aninh]

can you make a video guide about vuejs, nodejs? We are looking forward to it!!!

[andromilk]

When an element ends up moving up or down by using the function, we update our new array. Does this mean we also recreate the mapping with the new positioned elements by reinserting them into the unordered list? (Because we also need to take into account that the element which have changed position have take new indexes, so we have to readjust their id, index given to the callback functions, etc.) ?

[nickinspire]

Thanks bro, can you make a flutter tutorial please? I hope you see this comment

[ireqkub]

21:12 I wrote according to the video and it said that error. I attempted to find the cause of error. I read it and I don't understand it. But just putting a single semi-colon (;) end of the line, The error is gone :>
