In this case, the current implementation may not yield the expected background images due to improper concatenation. Let’s explore how we can enhance this code.

A Better Approach: Using Template Strings

To improve readability and manage concatenation more effectively, it’s highly recommended to utilize template strings. This method allows you to embed expressions within strings using backticks. Not only does this make the code neater, but it also brings clarity to the modification of URL paths.

Step-by-Step Solution

Define Your Data Properties: Ensure that you have defined your items and domain correctly.

Create a Method for URL Construction: Instead of handling the concatenation directly in the template, build a method that returns the desired style.

Utilize Template Strings: Implement template strings to concatenate the URL within that method.

Here’s how the refined code should look:

Benefits of This Method

Improved Readability: Using template strings instead of string concatenation makes your code significantly easier to read and debug.

Maintainability: By creating a method to handle the style logic, you can easily manage and modify your URL structure in one place.

Flexibility: The method can be extended or modified in the future, accommodating new requirements without changing multiple lines of code.
