遞歸刪除文件夾但排除命名文件夾

Question

以下代碼可幫助遞歸刪除文件夾。它刪除整個文件夾。

var deleteFolderRecursive = function(removePath) { 
    if(fs.existsSync(removePath)) { 
    fs.readdirSync(removePath).forEach(function(file,index){ 
     var curPath = path.join(removePath, file); 
     if(fs.lstatSync(curPath).isDirectory()) { 
     deleteFolderRecursive(curPath); 
     } else { // delete file 
     fs.unlinkSync(curPath); 
     } 
    }); 
    fs.rmdirSync(removePath); 
    } 
}; 

我怎麼能擴展它來刪除文件夾遞歸，而是以文件夾名稱不包括一些文件夾。假設名稱爲parentFolder的文件夾具有子文件夾名稱folderName1,folderName2，folderName3。 folderName1和folderName2及其所有文件將不會被刪除，如果我以下面的方式聲明。

var deleteFolderRecursive = function (removePath, excludeDirArray) { 
    // code here 
} 
deleteFolderRecursive(path, ['folderName1', 'folderName2']);

var deleteFolderRecursive = function(removePath, exclusive) { 
    var shouldDelete = function(pathUrl) { 
    if(exclusive && exclusive.length){ 
     return exclusive.indexOf(pathUrl) === -1; 
    } 
    return true; 
    } 

    if(fs.existsSync(removePath) && shouldDelete(removePath)) { // <-- use it here 
    fs.readdirSync(removePath).forEach(function(file,index){ 
     var curPath = path.join(removePath, file); 
     if(fs.lstatSync(curPath).isDirectory()) { 
     deleteFolderRecursive(curPath); 
     } else { // delete file 
     if(shouldDelete(file)) { // <-- optionally use it here 
      fs.unlinkSync(curPath); // if you want also files to not be deleted 
     } 
     } 
    }); 
    fs.rmdirSync(removePath); 
    } 
}; 

deleteFolderRecursive(path, ['folderName1', 'folderName1', 'myFile.txt']); // <-- also file
