    Performance Issue
    The consoleLog function uses a loop to check each line for console.log statements and breaks after finding the first occurrence. This could be inefficient for large files as it processes line by line. Consider using a more efficient text scanning or regex method that stops after the first match without looping through all lines.

    Walkthrough

    The changes introduce a new consoleLog stream to the hygiene function in build/hygiene.js, which detects stray console.log statements in files. This functionality iterates through file lines, logging error messages when such statements are found, including the file path and line number. The new stream is integrated into the existing processing pipeline, enhancing the function's ability to enforce coding standards by flagging unwanted console statements.

    File Change Summary
    build/hygiene.js Added a consoleLog stream to detect stray console.log statements, logging errors and integrating it into the hygiene checks.

    Poem

    In the code where rabbits play,
    Stray logs found, they mustn't stay!
    With a hop and a skip, we clean the way,
    For tidy scripts, we cheer and say,
    "Goodbye, console logs, you’ve had your day!" 🐇✨

    Error handling
    Add error handling to the consoleLog stream for better error management

    Add error handling for the consoleLog stream to manage exceptions or errors that
    might occur during the processing of files.

    build/hygiene.js [151]

    -.pipe(consoleLog);
    +.pipe(consoleLog).on('error', err => console.error('Error in consoleLog stream:', err));
     
    Suggestion importance[1-10]: 9

    Why: Adding error handling is important for robust stream processing and helps in managing exceptions effectively, which is a critical improvement for error management.

    9
    Maintainability
    Properly close the consoleLog stream to prevent memory leaks

    Ensure that the consoleLog stream is properly closed after its use to prevent memory
    leaks and ensure proper stream lifecycle management.

    build/hygiene.js [151]

    -.pipe(consoleLog);
    +.pipe(consoleLog).on('end', () => consoleLog.end());
     
    Suggestion importance[1-10]: 8

    Why: Ensuring the stream is properly closed is crucial for preventing memory leaks and maintaining proper resource management, making this a significant improvement.

    8
    Enhancement
    Improve the detection of stray console.log statements to avoid false positives

    Replace the regular expression used to detect console.log statements with a more
    robust pattern that accounts for comments or strings that might contain the text
    'console.log'. This will prevent false positives in the linting process.

    build/hygiene.js [114-118]

    -if (/^\s*console\.log/.test(lines[i])) {
    +if (/^\s*console\.log\(/.test(lines[i]) && !lines[i].includes('//') && !lines[i].includes('"console.log"') && !lines[i].includes("'console.log'")) {
       console.error(
         file.relative + '(' + (i + 1) + ',1): Stray console.log'
       );
       errorCount++;
       break;
     }
     
    Suggestion importance[1-10]: 7

    Why: The suggestion improves the accuracy of detecting stray console.log statements by accounting for comments and strings, reducing false positives. However, it could be further improved by using a more comprehensive parsing approach.

    7
    Best practice
    Use a specific custom event to avoid potential event collisions

    Consider using a more specific event than 'data' when emitting from the consoleLog
    stream. This can help in avoiding potential issues with event collisions in larger
    Node.js applications.

    build/hygiene.js [123]

    -this.emit('data', file);
    +this.emit('consoleLogProcessed', file);
     
    Suggestion importance[1-10]: 6

    Why: Using a specific custom event name helps avoid potential event collisions, which is a good practice in larger applications. However, the impact of this change is relatively minor.

    Possible bug
    Replace break with return in forEach to avoid syntax errors

    Ensure that the break statement inside the if block is replaced with return when
    using forEach, as break does not work inside forEach and will cause a syntax error.

    build/hygiene.js [119]

    -break;
    +return;
     
    Suggestion importance[1-10]: 9

    Why: This suggestion addresses a potential bug, as break is not valid within a forEach loop. Replacing it with return prevents a syntax error, ensuring the code functions correctly.

    9
    Enhancement
    Improve the regular expression for detecting console.log to handle spaces between console and .log

    Replace the regular expression used to detect console.log statements with a more
    robust pattern that accounts for possible leading characters before console.log,
    such as tabs or spaces, to ensure all instances are caught.

    build/hygiene.js [114]

    -if (/^\s*console\.log/.test(lines[i])) {
    +if (/^\s*console\s*\.log/.test(lines[i])) {
     
    Suggestion importance[1-10]: 8

    Why: The suggestion improves the robustness of the regular expression by accounting for spaces between console and .log, which enhances the accuracy of detecting stray console.log statements.

    8
    Replace traditional for loop with forEach for better readability and functional style

    Consider using forEach instead of a traditional for loop for iterating over lines,
    which can make the code cleaner and more expressive in a functional programming
    context.

    build/hygiene.js [113-120]

    -for (let i = 0; i < lines.length; i++) {
    +lines.forEach((line, i) => {
    +  if (/^\s*console\.log/.test(line)) {
    +    console.error(
    +      file.relative + '(' + (i + 1) + ',1): Stray console.log'
    +    );
    +    errorCount++;
    +    return;
    +  }
    +});
     
    Suggestion importance[1-10]: 7

    Why: Using forEach can make the code cleaner and more expressive, aligning with functional programming practices, although it is not a critical change.

    151-151: Good integration of consoleLog into the hygiene pipeline.

    The placement of consoleLog after the copyrights filter and before the final output is appropriate. It ensures that stray console.log statements are checked as part of the overall hygiene checks, aligning well with the PR objectives.

    Consider detecting all stray console.log statements in a file.

    The current implementation stops at the first stray console.log found due to the break statement. This might not catch multiple stray logs in the same file. Consider removing the break statement to continue checking all lines in the file.
