JavaScript Project

About

JavaScript is a versatile programming language widely used for creating dynamic and interactive web applications. Its ability to run on both the client and server sides makes it a cornerstone of modern web development.

This repository contains a collection of JavaScript projects and exercises, demonstrating fundamental concepts and applications of the language. Each folder is named with a number and a brief description of the topic it covers.

Key Features of JavaScript

1. Client-Side Scripting: JavaScript runs directly in the browser, allowing it to manipulate HTML and CSS dynamically. For example, it can update content, change styles, or respond to user interactions like clicks or keypresses.

2. Server-Side Capabilities: With environments like Node.js, JavaScript can also run on servers, enabling developers to build full-stack applications using a single language.

3. Event Handling: JavaScript can respond to browser events such as button clicks, mouse movements, or form submissions, making it essential for interactive web applications.

4. APIs and Libraries: JavaScript supports a wide range of APIs (e.g., DOM, Geolocation, Canvas) and libraries (e.g., React, Angular) to extend its functionality.

5. Asynchronous Programming: JavaScript supports asynchronous operations using Promises, async/await, and callbacks, which are crucial for tasks like fetching data from servers.

Getting Started

To run these projects, you can simply open the HTML files in your web browser. Most of the code will be contained within the HTML file itself or a linked JavaScript file.

1. Clone the repository to your local machine:

   git clone https://github.com/your-username/your-repository-name.git
   

2. Navigate to a project folder, for example:

   cd your-repository-name/07_counter_program
   

3. Open the index.html file in your browser.

Running Projects Requiring a Local Server

Some projects, like 75_fetch and 76_weather_app, may require a simple local server due to browser security restrictions. You can use a tool like http-server from npm:

1. Install http-server:

   npm install -g http-server
   

2. Navigate to the project folder and run the server:

   cd your-repository-name/76_weather_app
   http-server
   

3. Open the specified address in your browser (e.g., http://localhost:8080).
