Code Explanation

Here’s the code used to create the diamond pattern:

javascript
function printDiamond(n) {
    let pattern = '';
    const symbol = '?'; // Diamond symbol

    // Upper part of the diamond
    for (let i = 1; i <= n; i++) {
        pattern += ' '.repeat(n - i); // Add leading spaces
        for (let j = 0; j < 2 * i - 1; j++) {
            pattern += symbol + ' '; // Add diamonds with space
        }
        pattern += '\n'; // Move to next line
    }

    // Lower part of the diamond
    for (let i = n - 1; i >= 1; i--) {
        pattern += ' '.repeat(n - i); // Add leading spaces
        for (let j = 0; j < 2 * i - 1; j++) {
            pattern += symbol + ' '; // Add diamonds with space
        }
        pattern += '\n'; // Move to next line
    }

    console.log(pattern);
}

// Set the number of rows (height of the diamond)
let rows = 5; // You can change the number of rows here
printDiamond(rows);
