What might be a reason to check ISML syntax?

The rationale for checking ISML syntax primarily revolves around ensuring the accuracy of server-side scripting and preventing potential runtime errors when rendering templates. ISML (Interpreted Server Markup Language) is crucial for defining the structure and logic of the templates used in Salesforce Commerce Cloud (SFCC).

When ISML syntax is properly validated, it helps in confirming that the server-side scripting is correctly interpreted and executed by the SFCC platform. Any mistakes or errors in the syntax can lead to issues in rendering the components of the web application or even cause the application to fail altogether. By ensuring the syntax is valid, developers can maintain the integrity and functionality of the server-side code, which in turn affects the overall performance of the application.

While there are other aspects of development that may require attention—like CSS styles that are applied, CSRF token validation for security, or DOM manipulation—the primary focus of checking ISML syntax is related to the correctness of server-side logic and rendering processes within the SFCC ecosystem. This makes valid syntax essential for the effective execution of templates that rely on both frontend and backend integration.
