# Task
Now that we have learned the basics and the needed starting point for Functional Components in React, we will now go over a challenge that will help you get practical experience in creating components and getting familiar with coding components from scratch. 

## Your tasks are as follows:

- Initialize the count to 0 and create a function to increment it.

- Use the `useEffect` hook to log a message every time the count is updated.

- Fill in with the function to multiply count by and return that value.

- Add  two paragraphs here displaying the current count and the double count.

- Set the onclick method to a function that adds one to the count by calling `setCount`.


Hints:

- Use the `useState` hook to initialize the value to zero.

- Use the `console.log(count)` in the `useEffect` hook and have the `count` variable as a dependency.

- Create an arrow function that simply returns `count * 2`.

- Pass in `count + 1` to the `setCount` function which should be called in the `button`.

React is a popular JavaScript library for building user interfaces. It is developed and maintained by Facebook and is used by many large companies to create complex and interactive web and mobile applications. quckReact uses a virtual DOM to update the user interface efficiently and uses a declarative approach to programming, making it easy to reason about and predict the behavior of an application. React is known for its efficiency and flexibility and allows developers to create reusable components that can be quickly composed to build complex user interfaces.

The prompt provides a list of terms that are commonly used in React, a popular JavaScript library for building user interfaces. The terms include React, component, virtual DOM, JSX, constructor() method, render() method, state, setState() method, props, and binding methods. The prompt does not provide any additional context or information about these terms.

Now that we have become familiar with most of the React basics and how components work and integrate into the development of a website. Since we know that React components are loaded onto the main page and then can be dynamically updated which means that they go through a certain cycle of stages that can be intervened in and the behavior can be updated. 

This cycle can be manipulated through what are called lifecycle functions at different stages. React class component lifecycle methods are used for a variety of purposes, including performing setup tasks when a component is first rendered, updating a component in response to changes in props or state, and cleaning up any resources that the component is using.

Now that we have gone over the basics of class-based components, we will now explore a better and more concise way to write React components with functional components which are a lot more commonly used in React these days.

Functional components are a way to define components in React that are simple, lightweight, and only consist of a render function. They are a great choice for simple, presentational components that only need to render some JSX and don't have their own state or lifecycle methods.

In this section of the course, we'll look at how to use functional components with Hooks to manage state and other lifecycle events.

Now, we understand the basics of React with regards to the various kinds of components available and how to use them and exploit their lifecycle to our advantage in a webpage, we will now move on to some advanced topics. These topics will deal with topics like state management through Context API and the Consumer and Provider architecture in React and how these things make life easier in a production-level React App.

Then we will move onto Routing in react and how it all works to produce a navigable React App without having to reload the page. This involves studying an important React package called “react-router-dom” which we will get into in this section.
