My forEach loop is not working in ejs file while trying to fetch data from data base (mongodb) it contain a collection namely campground.but it work fine when I stored a collection of object in a array in myapp.js code.but when i m trying to implement through storing data in database it shows a error of campground.forEach is not a function

Here is my code:

myapp.js

var express=require("express");
var app=express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended:true}));
var mongoose = require('mongoose');
mongoose.connect("mongodb://localhost/campit");
var campgroundSchema=new mongoose.Schema({
  name:String,
  image:String
});

var campground=mongoose.model("campground",campgroundSchema);
app.get("/create",function(req,res){
   campground.find({},function(err,campgrounnd){
      if(err){
        console.log(err);
      }
      else{
        res.render("index.ejs",{campground:campground});

The find method in MongooseJS returns a Query object (reference). There are a few ways you can do searches and return results.

   campground.find().exec(function(err,result){
      if(err){
        console.log(err);
      }
      else{
        res.render("index.ejs",{campground:result});
      }
   });

I think you are conflicting variable name

var campground=mongoose.model("campground",campgroundSchema); // here is a campground
app.get("/create",function(req,res){
   campground.find({},function(err,result /* <-- */){ // the result is also campgrounnd
      if(err){
        console.log(err);
      }
      else{
        res.render("index.ejs",{campground:result/* <-- */}); // pass result instead campgrounnd
      }
    })
 });
