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

# Add the error handling

It’s now time to add error handling to the `App.js` file. When a user enters an invalid city name, our API should return an error instead of the property. In that scenario, the `error` message should be displayed instead of the `ShowWeather` component. All the error state functionality was included in the last lesson. To display the `ShowWeather` and `error`, we should use the ternary operator. The following code snippet shows how to add the `error` and `ShowWeather` by using the ternary operator:
```
{error ? (
  <h3 className="error">No data found :( </h3>
) : (
  <ShowWeather data={weatherData} />
)}
```
