Lifecycle hooks

Life cycle hooks are methods that let us alter the behavior of components at various stages of their life cycle. 

What is a component's lifecycle?

It's just the natural progression of the life of a component.

Thus, we can say that lifecycle hooks are points along this journey that each component needs to go through. At these specific points in a component's life, we can use these methods to alter a component's behavior.

The Vue team has chosen very descriptive names for these lifecycle methods. What follows is the list of lifecycle hooks organized in the order of the natural progression of a component's life:

• beforeCreate
• created
• beforeMount
• mounted
• beforeUpdate
• updated...
