Take a look at [async](https://github.com/caolan/async) or promises. Or any of the existing questions on SO about this. Remember to always check if your question has already been asked before. Also, please paste the code itself and not an image of it. Makes it easier for others to run your code and replicate the issue — cviejo, Jul 01 '16 at 13:02

Have a look at the async Library http://caolan.github.io/async/docs.html#.each

async.each(openFiles, function(file, callback) {

    // Perform operation on file here.
    console.log('Processing file ' + file);

     callback();

}, function(err) {

   if(!err){
     //because now my code will execute when for loop is done.
     //code here will run only after loop is done
    }

});
