nothing is being displayed when I preview the workspace in the browser.

let html = ' ';

for ( let i = 0; i < pets.length; i++ ) {
  let pet = pets[i];
  html += `
  <h2>${pet.name}</h2>
  <h3>${pet.type} | ${pet.breed}</h3>
  <p>Age:${pet.age}</p>
  <img src="${pet.photo}" alt="${pet.breed}">
`;
}

document.querySelector('main').insertAdjacentHTML('beforeend', html);

Mod edit: added markdown formatting for code readability. Check out examples for how to format your code in the forum in the "Markdown Cheatsheet" link below the comment box.

Hi Ryan,

Your code is looking good. When I test it I get the pets displayed on the page as expected. This means the issue is likely with something else, such as the pets array itself or the linking of your script files.

Some things to check:

  • Are both of your script files, pets.js and directory.js linked in your html?
  • Is pets.js linked before directory.js? (if directory.js comes first pets won't be defined yet and directory.js will have nothing to work with)

If this doesn't solve it, please post a workspace snapshot so I can take a closer look.
