I asked GPT what the source code does, was pretty impressed with the response
>This code is a JavaScript program that creates a "snow" animation on a web page. When executed, the code generates a number of white, circular elements (which represent snowflakes) and animates them to move across the page, creating the illusion of snow falling. The snowflakes are given random positions, sizes, and animations to make the effect more realistic.
Just the raw source code, or other parts of the website?
Which text did you use to ask it for a description?
Can you try progressively removing parts of the source code to see what the minimal version is which makes GPT say that the code renders a snow effect?
If you want to try things out it's free to use for now https://chat.openai.com/chat. Just pasting the raw source with no prompt is enough to get that description.
It is not entirely accurate (thankfully) the animations are done by CSS which is generated by JavaScript. But the way it understands context is pretty impressive.
