What is a helper in SFCC development?

In SFCC (Salesforce Commerce Cloud) development, a helper refers to reusable JavaScript functions designed to simplify and streamline common tasks throughout the application. These helpers are often used to encapsulate repetitive code, reducing redundancy and promoting maintainability. By creating a set of helper functions, developers can invoke complex logic or frequently used operations in a concise and standardized way, enhancing the efficiency of both development and debugging processes.

This approach aligns with best practices in programming, where common functionalities are abstracted into dedicated functions, thereby improving code organization and readability. Helpers can be utilized across various controllers and scripts within SFCC, serving as a toolbox for developers to easily access and implement essential functionalities without rewriting code.

The other options do not accurately define what a helper is in this context. A template for user input would relate more to form handling or layout rather than reusable functions. A static HTML resource refers to unchanging web content, which does not involve any JavaScript logic or reusable code. A method for API calls pertains to network communication and data retrieval, which is distinct from the purpose of a helper focused on encapsulating reusable JavaScript functionalities.
