Problem Explanation

• Using bracket notation simply write the return statement in the checkInventory() function.
• The following code block demonstrates the required syntax.

Example:

let juice = {
  apple: 1.15,
  orange: 1.45
};
function checkInventory(scannedItem) {
  return juice[scannedItem];
}

  apples: 25,
  oranges: 32,
  plums: 28,
