Which of the following statements about HubL and JavaScript is TRUE?
- a – HubL can be used in both the HTML + HubL and the JS sections of the module editor.
- b – HubL tags contain a “post_js_rendering” attribute so that you can pass JS data to HubL in modules.
- c – Module builders can choose between JavaScript and HubL to add module fields to their markup.
- d – JS written in the HTML + HubL section of the module editor will be repeated on a page for every instance of a module.
Explanation: The correct answer is JS written in the HTML + HubL section of the module editor will be repeated on a page for every instance of a module unless it is wrapped in a require_js statement. In HubSpot’s module editor, developers have the flexibility to include JavaScript (JS) code within the HTML + HubL section to enhance the functionality and interactivity of modules. When JS code is placed in this section, it becomes part of the module’s template and is consequently repeated on the page every time the module is instantiated, potentially leading to code duplication if not managed properly. To mitigate this issue and ensure efficient loading of JS resources, developers can utilize the require_js statement to conditionally load JS files only when needed, thereby avoiding unnecessary repetition of JS code across multiple instances of the same module. This approach optimizes page performance by minimizing redundant script execution and network requests, particularly in scenarios where modules are used multiple times within a single page or across different pages of the website. Therefore, the statement accurately highlights the behavior of JS code written in the HTML + HubL section of the module editor and emphasizes the importance of using the require_js statement to control the inclusion of JS resources and avoid unnecessary duplication.
