Turn your regular JavaScript code into a neural net

I see people hyping this on Twitter and I have no idea why. I don’t understand its applications.

i have no idea what this does? think of me as a stupid user on HN and explain to me what, why , where, how, when of this thing

What's the point of this ?

as if the AI slopper would know

I imagine to initialize a neural network with some hand coded behavior before tuning it on your dataset
