Why Learn to Create a Multiplication Table?

Creating a multiplication table in JavaScript is a great exercise because it:

Reinforces basic programming concepts: You practice loops, conditional statements, and DOM manipulation.
Builds a foundation for more complex projects: Understanding how to handle arrays and objects is crucial for advanced JavaScript tasks.
Enhances problem-solving skills: It’s a practical way to apply logic and algorithmic thinking.

Step-by-Step Guide to Creating a Multiplication Table in JavaScript

Creating a Multiplication Table in JavaScript:

1. Setting Up Your Environment
First, ensure you have a basic HTML setup. You can use any text editor and a browser to see the results.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Multiplication Table in JavaScript</title>
</head>
<body>
    <div id="multiplicationTable"></div>
    <script src="script.js"></script>
</body>
</html>

2. Writing the JavaScript Code

Create a script.js file and start by defining the size of the multiplication table you want. Here’s a simple example that generates a 10×10 table.

const createMultiplicationTable = (size) => {
    let table = '<table border="1">';
    for (let i = 1; i <= size; i++) {
        table += '<tr>';
        for (let j = 1; j <= size; j++) {
            table += `<td>${i * j}</td>`;
        }
        table += '</tr>';
    }
    table += '</table>';
    return table;
}

document.getElementById('multiplicationTable').innerHTML = createMultiplicationTable(10);

3. Adding Some Style

To make the table more visually appealing, you can add some CSS styles directly in your HTML or through an external stylesheet.

<style>
    table {
        width: 50%;
        margin: auto;
        border-collapse: collapse;
    }
    td {
        padding: 10px;
        text-align: center;
    }
</style>

4. Understanding the Code

Function Definition: The createMultiplicationTable function takes a parameter size to determine the table’s dimensions.
Nested Loops: The outer loop iterates through the rows, and the inner loop iterates through the columns, calculating the product of the indices.
DOM Manipulation: The resulting HTML string is inserted into the div with the ID multiplicationTable.
