The purpose of this exercise is to practice the core React concepts such as: creating components, passing data through props, working with state, rendering lists, and working with forms (controlled components).

To see the expected result for each iteration, refer to the solution example: React Training - solution.

• Fork this repo
• Clone this repo

$ cd react-training
$ npm install
$ npm run dev

• Upon completion, run the following commands:

  git add .
  git commit -m "done"
  git push origin main
  

• COLOQUE O LINK DO SEU REPOSITÓRIO NO PORTAL

Inside of the src/ folder, create a new folder named components.

Use the components folder to store all the components that you create in the following iterations.

Create and render an IdCard component with 6 props:

• lastName: A string
• firstName: A string
• gender: A string, 'male' or 'female'
• height: A number
• birth: A date
• picture: A string

Example:

<IdCard
  lastName='Doe'
  firstName='John'
  gender='male'
  height={178}
  birth={"1992-07-14"}
  picture="https://randomuser.me/api/portraits/men/44.jpg"
/>

<IdCard
  lastName='Delores '
  firstName='Obrien'
  gender='female'
  height={172}
  birth={"1988-05-11"}
  picture="https://randomuser.me/api/portraits/women/44.jpg"
/>

Expected Output:

Veja como tem que ficar.

Create a Greetings component with 2 props:

• lang: A string that can have values: "de", "en", "es" or "fr"
• children: A text

The component should display a greeting text in the chosen language.

Example:

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

Expected Output:

Veja como tem que ficar.

Create a Random component with 2 props:

• min: A number
• max: A number

The component should display a random integer in the range between the min and the max number.

Example:

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

Expected Output:

Veja como tem que ficar.

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

The component should take 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} />

Expected Output:

Veja como tem que ficar.

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

Create a CreditCard component that displays a rectangle with the information coming from the props.

The component should take 8 props:

• type: A string that can be "Visa" or "Master Card"
• number: A string that is the number of the credit card. For security reasons, you should only display the 4 last digits 😉
• 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 make the component look as close to the expected output as possible. You'll probably want 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}
  expirationYear={2019}
  bank="Name of the Bank"
  owner="Firstname Lastname"
  bgColor="#ddbb55"
  color="white"
/>

Expected Output:

Veja como tem que ficar.
