Sum component

• Replace <your_account> with your Github username in the DEMO LINK
• Follow the React task guideline

Task

Create a Sum component accepting OPTIONAL props a and b and rendering a paragraph with the text: "Sum of 2 and 1 is 3". Replace numbers with actual values. If a or b are not passed, set them to 0.

App should contains the next Sum components:

• a = 2 and b = 3
• a = 5 and b = -5
• just a = 10
• just b = 5
• no params at all

Extra task (optional): Add props validation using PropTypes library and defaultProps

Hint The linter requires you to put every JSX expression on the new line. So this markup:

<h1>The {color} is great!</h1>

should be rewritten like this:

<h1>{`The ${color} is great!`}</h1>

<h1>
  The
  {' '}
  {color}
  {' '}
  is great!
</h1>
