Jeremiah thinks this is a great idea, but has concerns about how it may slow down the site. What solution could Jeremiah employ to keep the functionality while maintaining the site speed?

 

• There is no solution to keep this functionality and avoid slowing down the page, resulting in decreased performance. Therefore, Jeremiah should recommend that Maria not use it.
• Use an open source web bundler to combine all the JavaScript on the homepage, placing it at the bottom of the page.
• Put the JavaScript that generates the site location in the HTML of the page where it’s needed, and keep non-essential JavaScript in the page footer.

 

Explanation: The correct answer is Put the JavaScript that generates the site location in the HTML of the page where it’s needed, and keep non-essential JavaScript in the page footer. Jeremiah can address Maria’s desire to contextualize the site’s homepage with the nearest car rental pickup spot while also mitigating concerns about site speed by strategically placing JavaScript code. By embedding the JavaScript responsible for generating the site location directly within the HTML of the page where it’s needed, Jeremiah ensures that this essential functionality loads efficiently and quickly. Meanwhile, non-essential JavaScript, such as scripts for analytics or third-party plugins, can be deferred and loaded asynchronously in the page footer, allowing critical content to render first without being blocked by slower-loading scripts. This approach optimizes the loading process, prioritizing essential functionality while maintaining overall site speed and user experience. By implementing this solution, Jeremiah enables Maria to enhance the site’s contextualization without compromising performance, ultimately achieving a balance between functionality and speed that benefits both users and search engine optimization efforts.
