Off topic, but that website was quite unusual.

Judging by the title, I was expecting an article about perennial plants with elongated stems or trunks that usually support branches and leaves. Instead, I was met with a series of code blocks, briefly making me wonder if the piece was discussing a novel data structure based on traditional trees. After a few moments, the code blocks were either substituted or supplemented with the actual page content, reminiscent of Jupyter Notebooks. After about 10 seconds, it became unclear whether all the content had fully loaded.

Not the most user-friendly experience, in my opinion.
