If you are coming from another async framework that does not work in the way described above and you are used to defining trivial compute-only *path operation functions* with plain `def` for a tiny performance gain (about 100 nanoseconds), please note that in **FastAPI** the effect would be quite opposite. In these cases, it's better to use `async def` unless your *path operation functions* use code that performs blocking <abbr title="Input/Output:...

   * might be null, or you need support for {@link List#set(int, Object)}, use {@link
   * Arrays#asList}.
   *
   * <p>Note that even when you do need the ability to add or remove, this method provides only a
   * tiny bit of syntactic sugar for {@code newArrayList(}{@link Arrays#asList asList}{@code
   * (...))}, or for creating an empty list then calling {@link Collections#addAll}. This method is
