const [state, useState] = useState("")
哦，無嘢喇，我唔知setState係咁定義

我錯
我錯唔計你錯useState hook用[a, setA]嚟命名係常見用法，只係我以為setState係一個專有method而唔係求其一個variable命名走出嚟
自己整
useState wrap住全部state變左class component 咁
useState wrap住全部state變左class component 咁通常複雜嘅都用class component
State方面好用啲，唔洗define 一堆 const getter setter
而且life cycle傳統啲，寫開Java / Swift 會易理解啲
Function就用嚟裝下嘢算

幾好
