difference between localStorage.getItem('color'); localStorage.color;

Is there a difference between : localStorage.getItem('color'); and localStorage.color;

because these are the results I get on my console when i delete the color property:

localStorage.getItem('color'); 
null
localStorage.color;
undefined```

no big difference. localStorage.getItem is a method defined of the localStorage object and returns the properties set in local storage and will return null if properties doesn't exist. on the other hand localStorage.color is accessing the property color in the localStorage object directly which will return undefined if that property doesn't exist just like any other object.
