This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
You can learn more in the Create React App documentation.

- {Instructor} Introduce child/parent component relationship, controlled inputs
- Create a new github repo called reacttodos, clone the repo to your computer and add the link to populi.
- Run "npx create-react-app ." inside /reacttodos.
- Create a new component in app.js and add it to the component as a child component:
-
- In ToDoComponent, implement the following functionality:
- There should be two text input fields, one dropdown input field (Hint: use and ), and a button. Every input field should store its current value in a useState variable. The input field should also receive its current value from the variable in useState, i.e. it should be a controlled component: <input type="text" value={title} onChange={(event)=>{ const newTitle = event.target.value setTitle(title) }}> The first text input field should set a state variable called title. The second text input field should set a state variable called description. The dropdown field should have 3 values "low", "medium" and "high" and should set a state variable called importance. The button should say submit and onClick, it should push a new object into a state variable called toDoList with the current values inputted by the user. E.G. If I type a title of "New Todo", a description of "My new todo", select an importance of "medium", and press submit, the state variable toDoList should look like this: [{ title: "New Todo", description: "My new Todo", importance: "medium" }] Finally, render the list of todo's stored in toDoList to the page.
