Build real-world React projects, from a to-do list and quiz app to weather dashboards and portfolios, while mastering components, state, props, API integration, and assessments at every level.

Become a React Developer

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

## 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} />
)}
```
We can now add this in the following widget:
