The Yoctopuce API provides almost identical functions to drive devices for all supported programming languages, regardless of the huge environment difference between them (take C++ and JavaScript, for example). But are all languages equally good ? Do they all provide the same perfs ? Let's look at this in detail, and expect some surprises...

We recommend this technique as a starting point, because it is generally more intuitive and less risky. There is, however, an alternative approach, sometimes more convenient: the event-based technique, using callbacks. This is the new API feature that we present today.
