June 4, 2024 - It’s worth reiterating that this is the first method invoked before the component is mounted to the DOM.

April 5, 2018What lifecycle methods are there in a stateless component?
1/ a functionnal component will works exactly like a class component with only a render method : every time any props changes the method is called to produce a new rendered tree
2/ You can override method in a class.
It can be usefull to override the shouldComponentUpdate method, especially if you've got a costly render method, but most of the lifecycle method are useless in a stateless component
componentDidMount/componentDidUpdate/componentWillUnmount can be usefull if you want to do something directly with the DOM.

August 12, 2024 - The mounting phase has three main lifecycle methods that are called in order: The constructor() method is called when the component is first created.
