For example, you are building a dictionary app where the entries are objects, and all the values are stored in a server-side database. The entries are visible client-side, so they should eventually be JavaScript objects. However, since the data is server-side, there are two ways to construct the object:

  1. Construct the entries objects via PHP, then pass the result to a .js script, which makes JavaScript objects from it.

  2. Construct the entries via JavaScript, calling AJAX methods on the object to request the specific information about the entry (e.g. definition, synonyms, antonyms, etc.) from the server.

The first way ends up constructing each entry twice, once via PHP and once via JavaScript. The second way ends up calling several AJAX methods for every construction, and opening and closing the database connection each time.

Is one preferable to the other, or is there a better way to do this?

    I use a rule of thumb, the less AJAX (on a page opener) the better.

    If you can push all information on the page load to the user, do it. Then use AJAX on subsequent calls. Otherwise the user-experience will suffer from AJAX (rather than benefit) as the page will take longer to load.
