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

# The nanoid

Nanoid is a `npm` package that generates a unique string each time we call the `nanoid` function.
> **Note:** You can read more about the nanoid function on the [official NPM website](https://www.npmjs.com/package/nanoid).

# Why we need nanoid

Each time we pass the `props` item in a component, it generates a child element. React needs a unique key to uniquely distinguish these child elements.

# How to install

Like all packages, we simply run the following command:
```
npm install nanoid
```
> **Note**: This step has already been done here.

# How to use

To generate the unique string, we simply call `nanoid` and pass this value as a prop, as we did in the code snippet below.

```
import {nanoid} from "nanoid"

id: nanoid()
```

Observe this in the following code:
