| // 1. Create empty output variable that will contain the gallery images | |
| let output = ''; | |
| // 2. Create a function `handleItem()` that accepts the array `item` (the Picsum image id) as a parameter | |
| const handleImageId = function(imageId){ | |
| // 3. In this new function, take the Picsum image id and create a valid img element that's 300px x 300px | |
| // <img src="https://picsum.photos/id/[imageId]/300/300" alt="Lorem Picsum Image"> | |
| output += `<img src="https://picsum.photos/id/${imageId}/300/300" alt="Lorem Picsum Image">` | |
| } | |
| // 4. Using Array.forEach(): loop through each Picsum image id, invoking handleItem() for each item. | |
| picsumIds.forEach(handleImageId); | |
| // 5. Using a method of your choice, output the image to `index.html` so that a gallery of all images is displayed on the page | |
