Javascript basic recursive for middleware

gistfile1.txt

var recursive = function(index,done,middlewares,props=null){
	console.log(index,'length',middlewares.length)
  if(index == middlewares.length){ 
  
    return done();
  }
  var next = index + 1;
  console.log('next',next);
  console.log('index',index);
  return middlewares[index](props,done,recursive.bind(this,next,done,middlewares))
}

var middlewares = [function(props,done,next){
	console.log('props',props);
  console.log('step 1');
  next({
  ...props,
  b : 2
  });
},function(props,done,next){
	console.log('props',props);
  console.log('step 2');
  setTimeout(function(){
  	next();
  },5000)
},async function(props,done,next){
   console.log('step 3');
  var test = function(){
    return new Promise(function(resolve){
      setTimeout(function(){
        resolve();
      },10000)
    })
  }
  await test();
  next();
},function(props,done,next){
   console.log('step 4');
  next();
}]

recursive(0,function(){
  console.log('done')
},middlewares,{
 a : 1
});
