Accessing `props` out of constructor

Question

I simply made a state object since there was no need of constructor. I accessed props in that state object as this.props , so here in this state object I am able to access the props using this keyword. Can someone state any reason for not using it the current way and defining a constructor. state={visibility: this.props.visibility}

got following result from babel.repl

我找到了答案，如果我们在构造函数中或在类https://michalzalecki.com/react-components-and-class-properties/中进行初始化，则没有任何区别
