* Continuing with Codecademy’s React course.
* Now it’s talking about the **component lifestyle** of React.
    * It consists of three ‘high-level’ parts.
        * Mounting.
            * When a component is put into the DOM for the first time.
        * Updating
        * Unmounting
            * When a component is removed from the DOM.
* **Lifecycle methods** are methods relating to the lifecycle. constructor() and render() are examples.
* **Single Responsibility Principal**. Not sure exactly what this is. Something got to do with constructor() methods.
* During the mounting phase, you call three lifecycle methods in this order.
    * 1. The constructor
    * render()
    * componentDidMount()
* This stuff is pretty difficult. I’m going through the tutorial, but the concepts are tough to understand.
* **SPA **stands for Single Page Application. https://www.youtube.com/watch?v=zbHb1c_gII4&list=WL&index=5
