HTML Implementation Example

Integrating a Simple Data Consolidation Module

Below is an example of how a simple data consolidation module might be implemented using HTML and JavaScript:

// Data Consolidation Module Example
// Function to consolidate data from multiple sources
function consolidateData(source1, source2, source3) {
    // Combine data from sources
    let consolidated = [...source1, ...source2, ...source3];
    
    // Remove duplicates
    let uniqueData = consolidated.filter((item, index) => 
        consolidated.indexOf(item) === index
    );
    
    return uniqueData;
}

// Example usage
const data1 = ['item1', 'item2', 'item3'];
const data2 = ['item2', 'item4', 'item5'];
const data3 = ['item5', 'item6', 'item1'];

const consolidatedData = consolidateData(data1, data2, data3);
console.log(consolidatedData);
// Output: ['item1', 'item2', 'item3', 'item4', 'item5', 'item6']
