All Themes // Bridge #15
The connection

Both propagate information backward through a structure to determine what needs updating. React traces from changed leaves back to root; backprop traces from loss back to input weights via the chain rule. Caveat: Backprop is a mathematical operation (chain rule, partial derivatives) with no direct DOM equivalent.

Why "Intuition"?

Intuition bridges share a useful mental model, but the underlying mechanisms differ. Use with care.
