Rosetta Code Challenges - Align columns

Tell us what’s happening:

I’m trying to display the aligned text properly for different alignments focusing on displaying columns to the right also the left and center. I formatted the console to the correct alignments but my code still doesn’t pass. Is it possible if you can explain to me where I went wrong so I can figured out how I can correct this issue. Thanks and have a blessed day.

Your code so far

function formatText(text, alignment = 'left') {
    // Step 1: Split each line into fields
    const lines = text.map(line => line.split('$'));

    // Step 2: Determine the maximum width of each column
    const maxWidths = lines[0].map((_, colIndex) => 
        Math.max(...lines.map(line => (line[colIndex] || '').length))
    );

    // Step 3: Define alignment functions
    // Left justification: pad spaces to the right of the field
    const leftJustify = (field, width) => field.padEnd(width, ' ');
    
    // Right justification: pad spaces to the left of the field
    const rightJustify = (field, width) => field.padStart(width, ' ');
    
    // Center justification: calculate and pad spaces on both left and right
    const centerJustify = (field, width) => {
        const totalPadding = width - field.length;
        const leftPadding = Math.floor(totalPadding / 2);
        const rightPadding = totalPadding - leftPadding;
        return ' '.repeat(leftPadding) + field + ' '.repeat(rightPadding);
    };

    // Step 4: Choose the appropriate alignment function
    let justify;
    if (alignment === 'left') {
        justify = leftJustify;
    } else if (alignment === 'right') {
        justify = rightJustify;
    } else if (alignment === 'center') {
        justify = centerJustify;
    } else {
        throw new Error("Invalid alignment. Choose from 'left', 'right', or 'center'.");
    }

    // Step 5: Align each field in the columns for every line
    const alignedLines = lines.map(line => 
        line.map((field, colIndex) => justify(field || '', maxWidths[colIndex])).join(' ')
    );

    // Step 6: Reassemble the text by joining lines with newline characters
    return alignedLines.join('\n');
}

// Test the function with the given text
const testText = [
    'Given$a$text$file$of$many$lines',
    'where$fields$within$a$line$',
    'are$delineated$by$a$single$"dollar"$character',
    'write$a$program',
    'that$aligns$each$column$of$fields',
    'by$ensuring$that$words$in$each$',
    'column$are$separated$by$at$least$one$space.',
    'Further,$allow$for$each$word$in$a$column$to$be$either$left$',
    'justified,$right$justified',
    'or$center$justified$within$its$column.'
];

console.log("Left Justified:\n");
console.log(formatText(testText, 'left'));
console.log("\nRight Justified:\n");
console.log(formatText(testText, 'right'));
console.log("\nCenter Justified:\n");
console.log(formatText(testText, 'center'));
