What is recommended practice for creating arrays of structured data?

I was playing around with the simpleDataLogger and found that the Int16Array() used in the example is efficient (especially pushing new values onto the array), however, what is the recommendation if you have a tuple like: 32 bit timestamp and 2 16 bit temperature values, and want to maintain an array of these, to make a random example?

Being a 'C' programmer, I'd define a structure containing the 3 values and simply create an array of structures, keeping head and tail indexes to add to the array. Very efficient. I suspect those who have 'internal' knowledge and experience with Espruino would come up with a more efficient implementation than I would... :-)
