Reference JSON object with forEach in node.js

Question

In the view, I want to loop through list and render resolved_title of all list items. This is the JSON object.

{ status: 1,
  complete: 1,
  list: 
   { '56777886': 
      { item_id: '56777886',
        resolved_id: '56777897',
        given_url: 'https://youtu.be/5XD2kNopsUs',

  error: null,
  search_meta: { search_type: 'normal' },
  since: 1444662727 }

And below is the view, but I'm getting body.list.forEach is not a function error. What am I doing wrong?

<% body.list.forEach(function(item) { %>
    <p><%= item.resolved_title %></p>
<% }) %>

list is not Array is Object and in Object there is not method forEach, try this

<% Object.keys(body.list).forEach(function(key) { %>
    <p><%= body.list[key].resolved_title %></p>
<% }) %>

But better format data in your controller and then pass it to view, like so

var titles = Object.keys(body.list).map(function(key)
  return body.list[key].resolved_title;
});

// pass titles to view 

<% titles.forEach(function(title) { %>
    <p><%= title %></p>
<% }) %>
