What syntax does ISML use for expressions?

ISML (Interpreted Server-side Markup Language) uses the syntax ${expression} for its expressions. This syntax allows developers to embed dynamic content directly within ISML templates. When the ISML engine processes the template, it evaluates the expression inside the curly braces and replaces it with the corresponding value at runtime.

This syntax is important because it differentiates between static content and dynamic content that needs to be generated based on the current state of the application. By using this format, developers can easily include variables, perform operations, and access data from the server-side within their HTML-like ISML files.

The other choices involve different patterns not recognized by ISML for expressions. Thus, the specific use of ${expression} is integral to how developers can seamlessly integrate logic with presentation when working with Salesforce Commerce Cloud templates.
