- [Instructor] The React component lifecycle…provides functions that are invoked at specific times…during the rendering lifecycle.…Let's explore some of these.…To understand the component lifecycle more,…I really like this handy chart.…It describes all of the functions…that are called right before a component mounts,…whenever a component updates, and when it unmounts.…So mounting and unmounting just means whenever it's added…to the dom, and whenever it's taken away.…So if I go back to our code, and I look…at our library component, I can add some…of our component lifecycle methods to this class.…
Component lifecycle methods are only available…when using class syntax, so you can't use them…with function components.…Now the only required method…of the component lifecycle is render.…Whenever the props or state of the app changes,…render will be called.…The next method is the constructor.…So if I had a constructor here,…instead of initializing state as this static property,…the constructor is called before the component is mounted,…
