How to use default props in React

If you dont want to specify props every time you use an element, you can also specify defaults for these items. This can also be useful to remember which props are needed per component.

This can be added with the component name and then using the defaultProps.

In the following example the defaultProps are added but they are not displayed in the ShoppingCart object.

HTML

<div id="challenge-node"></div>

const ShoppingCart = (props) => {
  return (
    <div>
      <h1>Shopping Cart Component</h1>
    </div>
  )
};
// Change code below this line
ShoppingCart.defaultProps = { items: 0 }
ReactDOM.render(<ShoppingCart />, document.getElementById('challenge-node'));
</script>

For a long time it had seemed to me that life was about to begin - real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, or a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life.

Random CSS Property

inset-inline-start

The inset-inline-start CSS property defines the logical inline start inset of an element, which maps to a physical offset depending on the element's writing mode, directionality, and text orientation. It corresponds to the top, right, bottom, or left property depending on the values defined for writing-mode, direction, and text-orientation.
