Quiz App using HTML CSS, JavaScript & React Js With Source Code
Introduction :
React-based Quiz App provides an interactive and engaging platform for users to test their knowledge across a variety of topics. Structured with modularity in mind, the app seamlessly renders dynamic quiz questions and answer options, offering immediate feedback on user responses. Users can interactively choose answers to quiz questions, with the Answers.jsx component dynamically updating visual feedback for correct and incorrect responses. The intuitive interface ensures an engaging quiz experience. The Main.jsx component manages user scores, providing immediate feedback on correct answers and dynamically updating the overall score. Users can track their progress as they move through the quiz. The Popup.jsx overlay adds an element of user interaction by offering a welcoming introduction at the start of the quiz. Upon completion, it dynamically adjusts its content to congratulate users, display scores, and prompt them to restart the quiz, enhancing the overall user experience. The Data.js file serves as an external data source, containing an array of objects representing quiz questions, answer options, and correct answers. This modular approach allows easy modification and expansion of quiz content without altering the core application code. The Main.jsx component dynamically renders quiz questions and answer options based on the user’s progression, ensuring a varied and adaptable quiz experience.
Explanation :
Answers.jsx
The Answers.jsx component encapsulates the logic for presenting answer options and handling user responses. The user interface allows users to select an answer by clicking on one of the provided options (A, B, C, D). The component dynamically updates the visual feedback for correct and incorrect answers, providing a visually engaging quiz experience.
Main.jsx
The Main.jsx component serves as the central hub, managing the flow of the quiz. It orchestrates the presentation of questions, answer options, and controls user progression through the quiz. The component uses the Answers component to render answer choices and includes logic to handle user responses, score calculation, and the transition to the next question. The integration of a popup component enhances the user experience by providing feedback on quiz completion.
Popup.jsx
The Popup.jsx component creates an overlay that serves multiple purposes within the quiz application. Initially displayed at the start of the quiz, it provides a welcoming introduction and prompts users to start the quiz. Upon completion of the quiz, the popup dynamically updates its content to congratulate users, display their score, and offer the option to restart the quiz. The Fade component adds a visual transition effect, enhancing the overall user interface.
Data.js
The Data.js file contains an array of objects, each representing a quiz question along with its answer options and the correct answer. This external data source ensures modularity and flexibility, allowing for easy expansion or modification of the quiz questions without directly modifying the application code.
