componentDidMount() in React

Docs Resource

The componentDidMount() is a built-in method for React.Component objects

It is one of a few methods that are called during the lifecycle of a component see the image below for visual of a lifecycle.

The above can be found here to use interactively: https://projects.wojtekmaj.pl/react-lifecycle-methods-diagram/

These methods can be overridden with custom logic for us to run code when something happens in the lifecycle

For example, we can run code when a component is created and starting the Mounting phase by adding in a constructor() method in the code.

For this example, we’re overriding the componentDidMount() method which will fire when a component “mounts” correctly.
