Why Destructing or assigning value to the variable does not work outside the render() Method?

Full Stack JavaScript Techdegree Graduate 16,700 PointsWithin a class Component, the render() method is what actually reads or examines the props. If you try to destructure props outside of the render() method, it won't work because our class Component doesn't have access to the props outside of render().
However, when we destructure within render(), we are actually using the props parameter passed in from whichever component passed the props.
There is some React "magic" going on here (really it's just React abstracting away the code that takes care of passing around props), which is why we don't actually see the props passed to render() like we do in a functional Component.
