You can use async library for this.then go for async.eachSeries.

You need to do npm install async first

Here is the example:

var async = require('async');
async.eachSeries(yourarray,function(eachitem,next){
// Do what you want to do with every for loop element
next();
},function (){
//Do anything after complete of for loop
})
