ES6 Homework

You have to modify file index.js and create the methods for Shop Cart:

• add(item, count) – method should add the item to the cart;
• remove(item) – method should remove the item from the cart;
• clear() – method should clear the cart (remove all items);
• setCount(item, count) – method should change quantity for item. If the method receive count below or equal zero, then it should throw Exception;

Important! You should change only index.js file.

To check your work we created a file with Jest tests. You can run tests with npm command: npm run test.

Your work will be successful if all tests are green.
