Let's Write React Hooks From Scratch

A deep dive into how React Hooks work internally, starting from a naive array-based implementation and progressing to a linked list model that mirrors React's actual source code. The post explains why hooks must be called in the same order every render (array/linked list index shifting), shows how component state is tracked via a global current component reference, and walks through React's actual Hook type definition with its `next` pointer. Code examples build incrementally from a simple global array to a Component class with a linked list of Hook nodes.
