Lifecycle Methods

React offers a number of lifecycle methods that can be called at different times in a component’s lifecycle. These can be implemented in React class components.

The lifecycle of a component starts as soon as it is instantiated or mounted. In other words, when it is found in the render() method of a parent component that is part of a returned component tree. The component’s lifecycle ends if it is removed from the tree of components that will be rendered. Additionally, there are lifecycle methods that react to updates or errors as well as being unmounted.
