functionControls(){ const increasePopulation=useBearStore((state)=>state.increasePopulation)return<button onClick={increasePopulation}>one up</button>} 1. 2. 3. 4. 如此一来,你在 <Controls /> 中调用修改 increasePopulation
注册和销毁时机分别是 subscribe 与destroy 函数调用时,这个实现很简单、高效。对应代码就不贴了,很显然,subscribe 时注册的监听函数会作为 listener 添加到 listeners 队列中,当发生 setState 时便会被调用。 最后我们看 createStore 的定义与结尾: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 function create...
