JavaScript Calculator Project Guide

This guide will walk you through creating a simple JavaScript calculator. Whether you're a beginner or looking to enhance your JavaScript skills, this project is a great way to practice your coding abilities.

Project Overview

A calculator is a fundamental tool that can help you understand various JavaScript concepts, such as variables, operators, functions, and event handling. In this project, you will build a calculator that can perform basic arithmetic operations like addition, subtraction, multiplication, and division.

Getting Started

Before you begin, make sure you have a basic understanding of HTML, CSS, and JavaScript. You will also need a text editor or an Integrated Development Environment (IDE) to write your code.

Step 1: Set Up Your Project

Create a new folder for your project and inside it, create three files:

index.html
style.css
script.js

Step 2: HTML Structure

In your index.html file, set up the basic structure of your calculator. Use a combination of <div>, <input>, and <button> elements to create the calculator interface.

<div id="calculator">
  <input type="text" id="display" disabled>
  <button onclick="clearDisplay()">C</button>
  <button onclick="appendNumber('1')">1</button>
  <button onclick="appendNumber('2')">2</button>
  <!-- Add more buttons for numbers and operations -->
</div>

Step 3: CSS Styling

In your style.css file, add some basic styling to make your calculator look good. You can customize the colors, fonts, and layout to your preference.

#calculator {
  /* Add your styles here */
}

Step 4: JavaScript Logic

In your script.js file, write the JavaScript code to handle the calculator's functionality. This will include functions to append numbers, perform operations, and display results.

function appendNumber(number) {
  // Add your code here
}

function clearDisplay() {
  // Add your code here
}

// Add more functions for other operations
