QVarLengthArray is a container class with interesting semantics, not found in any container from the Standard Library. Like an array, it stores elements contiguously in memory. Like a vector, it has dynamic size. But unlike a vector, it does not necessarily store them in heap-allocated memory.

How does it work then? Well, watch the video to learn more!
