Stopwatch App in React JS

Overview

This project is part of the Codevixens Frontend Development Challenge (Day 8). A simple stopwatch application built using React. It demonstrates how to manage state, handle events, and use lifecycle methods to create a functional timer.

Features

• State Management: Uses React's useState hook to manage the elapsed time and the running state of the stopwatch.
• Event Handling: Handles button click events for starting, stopping, and resetting the stopwatch.
• Lifecycle Methods: Uses useEffect to manage the timer interval, starting it when the component mounts and clearing it when the component unmounts or when the stopwatch is stopped.
• Timer Logic: Implements logic to increment the time every millisecond while the stopwatch is running.
• User Interface: Provides a display for the elapsed time and buttons for Start, Stop, and Reset.
• Styling: Uses CSS to style the application for a visually appealing look.

Installation

1. Clone the repository:

git clone https://github.com/gideonagyage/Stopwatch-App.git

2. Navigate to the project directory:

cd Stopwatch-App

3. Install dependencies:

npm install

Usage

1. Start the development server:

npm start

2. Open your browser and navigate to

http://localhost:3000.

How it Works

The Stopwatch component is the main component that handles the following:

1. State Management: Manages the elapsed time and the running state of the stopwatch using useState.
2. Event Handling: Handles button clicks for Start, Stop, and Reset.
3. Timer Logic: Uses useEffect to create a timer interval that updates the elapsed time every millisecond.
4. UI Rendering: Renders the time display and the control buttons.

Key Concepts

1. State Management: Managing the data and UI state of the React application.
2. Event Handling: Responding to user interactions with the application.
3. List Rendering: Dynamically rendering lists of data in the React application.
