component is just an independent, re-useable piece of code. 

​

import { useEffect, useState } from "react"

Here we are using the `import` statement to import `hooks` from the `React` library.

​

useState() : 

This function is built into React, to store the state in a component.

The function returns an array.

The array contains the initial state value at index 0 and a function that modifies the state at index 1.

`const [ state, setState ] = useState([])`

​

useEffect() :

This function is built into React, to ***observe*** state. 

It allows you to observe state and run some instructions when state changes.

Since the `useState` function performs the first change in state, you can observe that.

​

`useEffect(

    () => {console.log(state) // View the initial state of tickets},

    [] // When this array is empty, you are observing initial component state

)`
