// JavaScript Example
function calculateSum(a, b) {
    return a + b;
}

function generateFibonacci(n) {
    let fib = [0, 1];
    for (let i = 2; i < n; i++) {
        fib[i] = fib[i-1] + fib[i-2];
    }
    return fib.slice(0, n);
}

// Test the functions
console.log("Sum of 15 and 27:", calculateSum(15, 27));
console.log("First 10 Fibonacci numbers:", generateFibonacci(10));

// Array operations
const numbers = [5, 12, 8, 130, 44];
console.log("Original array:", numbers);
console.log("Filtered (greater than 10):", numbers.filter(num => num > 10));
console.log("Sorted array:", numbers.sort((a, b) => a - b));

How to Use the Real-Time Program Output Generator

Our Real-Time Program Output Generator is a powerful tool designed for developers, students, and educators to simulate code execution and generate output instantly. Follow this guide to make the most of all its functionalities.

1. Getting Started

Begin by selecting your programming language from the dropdown menu. The tool currently supports JavaScript, Python, HTML, Java, C++, and PHP. Each language has specific syntax handling and execution patterns.

2. Writing or Loading Code

You can either type your code directly into the input area or use one of our pre-built snippets from the Code Snippets section. These snippets provide common programming patterns that you can modify for your needs.

3. Adjusting Parameters

Execution Speed: Control how fast the output generates with the slider
Error Simulation: Test how your code handles different error types
Output Format: Choose how results are displayed (plain text, JSON, HTML, or table)
Variable Values: Set custom values for variables in your code

4. Generating Output

Click the "Generate Output" button to execute your code. With Auto-Execute enabled, the output updates in real-time as you type. The tool simulates actual code execution, including console logs, function returns, and error handling.

5. Working with Results

Once output is generated, you can:

Copy the results to clipboard with one click
Export the output as a text file
View execution statistics (time, lines, characters)
Access previous executions from the history panel

6. Advanced Features

Explore the Advanced Settings section to:

Switch between light and dark output themes
Customize the output prefix for better readability
Reset all settings to their default values
Toggle real-time updates on or off

Best Practices

For optimal results:

Use the variable values field to test different inputs without modifying code
Experiment with error simulation to understand debugging scenarios
Save time by starting with relevant code snippets
Adjust execution speed to simulate different processing conditions

This tool is perfect for testing algorithms, demonstrating code behavior, teaching programming concepts, and debugging practice. The real-time functionality provides immediate feedback, making it an invaluable resource for both learning and development workflows.
