Future calls to render() will reuse the existing tree and update it in-place in the DOM. Internally, render() will calculate the difference from previous outputted structures in an attempt to perform as few DOM operations as possible.
So the REST API calls belong to actions. The complete workflow is as follows: Component triggers an action. The action creator runs an asynchronous server request, and the result goes to the dispatcher as a payload. The store listens to the action, the corresponding action handler receives the...

Keys themselves should be a unique number or string; so if a React Component is the only child with its key, then React will repurpose the DOM Element represented by that key in future calls to render().Let’s demonstrate this with a simple list of todos rendered with React:...
memoizedFn(2)// calls `calculateResult` 当计算功能是确定性时,Memoization仅适用于函数,也就是说,指定相同的输入它总是返回相同的结果。例如,sum函数返回其参数总和的函数是确定性的: constsum = (a, b) => a + b 非确定性函数的示例是用于计算当前时间的timeAgo函数Date.now。每次调用时,该函数都会返回...
