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.

Building Real-World Projects with React

We’ll now add a dynamic background to the `ShowWeather` component that changes color based on the value of the `tempInCelcius` variable.

## Change color with respect to temperature

In our background, we give three breakpoints:
- If `tempInCelcius` is less than 10
- If `tempInCelcius` is greater than 10 but less than or equal to 30
- If `tempInCelcius` is greater than 30

We add three colors for these three breakpoints. Feel free to add any color. To make it functional, we use the `useState` hook to track the state. We also use the `useEffect` hook to call the `dynamicBackground` function each time the `tempInCelcius` changes. The following snippet shows how to create the `dynamicBackground` function:
