Function to get both pages and posts

[David]

Working on the VP0.2 – updating the model, completed. I wanted to create a function
that could be used to select both pages and posts as suggested in the video.
in the model.js there is a model.getPosts function. I added a modified version to
select both posts and pages but when I run that function I get this error

Uncaught TypeError: model.getLocalStore is not a function
    at Object.model.getContent (model.js:44)
    at model.js:50
model.js:17 Uncaught TypeError: model.updateLocalStore is not a function
    at Object.model.init (model.js:17)
    at Object.vanillaPress.init (app.js:20)
    at app.js:26

Here is the code

model.getPosts = function() {

  var posts = model.getLocalStore().posts;
  return posts;

}
//*****************************************************
//my code to condense getting pages and posts in the same function
 var whichType ='';
 model.getContent = function(whichType) {
    if (whichType === 'posts'){
      console.log(model.getLocalStore().posts);
   }
}
//******************************************

console.log(model.getContent('posts'));

Here is the complete page
