  gender='female'
  height={172}
  birth={new Date("1988-05-11")}
  picture="https://randomuser.me/api/portraits/women/44.jpg"
/>

Output

Iteration 2 | Component: Greetings

Create a Greetings component with 2 props:

• lang: A string that could be ,"de","en","es","fr"
• children: A text

Example

<Greetings lang="de">Ludwig</Greetings>
<Greetings lang="fr">François</Greetings>

Output

Iteration 3 | Component: Random

Create a Random component with 2 props:

• min: A number
• max: A number

Example

<Random min={1} max={6}/>
<Random min={1} max={100}/>

Output

Iteration 4 | Component: BoxColor

Create a BoxColor component that displays a rectangle with a background color based on props. For this, you will need a inline style (documentation).

It takes 3 props:

• r: A number between 0 and 255 representing the amount of red
• g: A number between 0 and 255 representing the amount of green
• b: A number between 0 and 255 representing the amount of blue

Example

<BoxColor r={255} g={0} b={0} />
<BoxColor r={128} g={255} b={0} />

Output

As a bonus, you can also display the hex values of the color (ex: #ff0000 for red).

Iteration 5 | Component: CreditCard

Create a CreditCard component that displays a square with a background color based on props. For this. You will need a styled component.

It takes 8 props:

• type: A string that can be "Visa" or "Master Card"
• number: A string that is a number of the credit card. You will only display the 4 last digits for security reasons 😉
• expirationMonth: A number that represents the month, between 1 and 12
• expirationYear: A number that represents the year
• bank: A string that represents the name of the bank
• owner: A string that represents the name of the owner
• bgColor: A string for the background color of the card
• color: A string for the text color of the card

Take your time to do as close to the output. You probably have to use flexbox.

Example

<CreditCard
  type="Visa"
  number="0123456789018845"
  expirationMonth={3}
  expirationYear={2021}
  bank="BNP"
  owner="Maxence Bouret"
  bgColor="#11aa99"
  color="white" />
<CreditCard
  type="Master Card"
  number="0123456789010995"
  expirationMonth={3}
  expirationYear={2021}
  bank="N26"
  owner="Maxence Bouret"
  bgColor="#eeeeee"
  color="#222222" />
<CreditCard
  type="Visa"
  number="0123456789016984"
  expirationMonth={12}

  bank="Name of the Bank"
  owner="Firstname Lastname"
  bgColor="#ddbb55"
  color="white" />

Iteration 13 | List and Keys - FaceBook (Simple)

Create a FaceBook component that displays the list of all profiles from src/data/berlin.json. You will probably have to write:

import profiles from './data/berlin.json';

Example

<FaceBook />

Output (you should see about 28 profiles)

Iteration 14 | List and Keys - FaceBook (Advanced)

On your FaceBook component, add as many buttons as you have country. Then, when the user clicks on one of the buttons (example: 'USA'), add a blue background to all the profiles where their country is the one selected.

Example

<FaceBook />

Output (you should see more profiles and more countries)

Example of extra iterations:

• By default, only display the picture. Then, when a user clicks on a picture, display more information
• Add sort buttons
• Add a search input

Iteration 15 | Form - SignupPage

Create a SignupPage component with the following elements:

• An input "email" (bonus: make the input green/red when the email is valid/invalid)

• A select input "nationality" (possible values: "en","de","fr")
• A text "Hello", "Hallo" or "Bonjour" based on the selected nationality
• A text "Your email is john@doe.com"

For this, you will need 3 states:

• email
• password
• nationality

If you want to include Bootstrap with Reactstrap, you should run

npm install reactstrap bootstrap

And add the following line in src/index.js

import 'bootstrap/dist/css/bootstrap.min.css';

Example

<SignupPage />
