+```smart header="Evaluation of default parameters"
+In JavaScript, a default parameter is evaluated every time the function is called without the respective parameter. In the example above, `anotherFunctions()` is called everytime `someMessage()` is called without the `text` parameter. This is in contrast to some other languages like Python, where any default parameters are evaluated only once during the initial interpretation.

 Old editions of JavaScript did not support default parameters. So there are alternative ways to support them, that you can find mostly in the old scripts.
