Understanding and Fixing the Issue of Populating Every Div in JavaScript

When working with JavaScript to dynamically create and structure HTML content, developers can sometimes encounter frustrating issues. One such problem is when multiple divs are created, but all contain the same elements instead of individual ones. This guide walks you through the common pitfall of populating only the first div and presents a solution for achieving distinct divs for your content.

The Problem

Imagine you are developing a web application that fetches data via an API. Your goal is to create several div containers that each feature an image and a title associated with particular data. As you loop through your API results, you find that while multiple divs are being created, only the first div is actually populated with the corresponding image and title. Each additional div simply ends up with the same elements as the first.

The Expected Structure

The desired HTML structure would look something like this for multiple items:

Each div should have its own unique image and title based on the loop's iteration over the fetched data.

The Solution

The key to solving this problem lies in correctly appending the created elements to their respective parent divs. Instead of appending all items to the first div, you ensure that each div receives its own title and image by modifying your JavaScript code slightly. Let's break this down step by step.

Step-by-Step Guide

Create the Box Div: Within your loop where you're processing each item from the API, create a unique div for each item.

Append Child Elements Correctly: Instead of appending child elements to the box selector directly, ensure you append the title and image to the newly created box div.

Correct Structure: Finally, append this box div to your container.
