Gain insights into creating five dynamic applications with ReactJS. Delve into hooks, APIs, and localStorage while building projects like to-do lists, quizzes, memory games, portfolios, and GitHub profiles.

ReactJS is one of the most well-known JavaScript frameworks. It was created by Facebook (now Meta). Being component-based and drawing on the most recent theories behind design systems, it allows you to design frontend software quickly and create dynamic user interfaces.

This course takes a project-oriented approach. You’ll start by building a “My To-do List” application, using localStorage, useEffect, and useState hooks, as well as setTimeout and nanoid. Then, you will build a “Quiz” application while learning to use the confetti package and ternary operator. Next, you’ll cover fetch API and build the “Pretty Sunny” project. Next, you’ll create the “Asia Explorer” memory game, creating catchy effects by dynamically adding class names. Then, you will implement a “Personal Portfolio” application. Finally, you will create a “GitHub Readme” profile to help you showcase your projects on GitHub.

Ultimately, you’ll be able to highlight your achievements on your resume, thus boosting your chances of landing a job.

Creating Five Impactful Applications with ReactJS

# Set the items

We must save the item each time the status of our `toDoList` changes (by adding new items or deleting old ones). We have `useEffect` in React to help us out. It takes two arguments:

- The `function` argument is called by using a hook.
- The `dependency` argument prevents `useEffect` from rendering each time. It only allows it to render when there’s a `dependency` change. In our case, the `dependency` is `toDoList`.

The syntax for the `useEffect` hook is the following:
```
useEffect ( function , [ dependency] )
 ```

In our case, the `key` is `TASK` and the value is `stringifyToDoList`. 

Because `localStorage` saves data in JSON format and `JSON.stringify` converts objects to JSON, we use `JSON.stringify`.
```
useEffect(() => {
    const stringifyToDoList = JSON.stringify(toDoList)
    localStorage.setItem("TASK", stringifyToDoList );
}, [toDoList]);
```
