Something strange is happening. In the lib.dom.d.ts file, the type for localstorage.getItem shows as 'string | null', but in my app it always returns a string. Why is this discrepancy occurring?

Take a look at the documentation: https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage
If you decide to utilize a JSON object within the localStorage, remember that you have access to both the JSON.stringify() and JSON.parse() methods.
When it comes to storing an object in localStorage, follow this syntax:
localStorage.setItem('token', JSON.stringify(user));
For retrieving an object from localStorage, use the following code:
user = JSON.parse(localStorage.getItem('user'));
By employing these techniques, you can ensure that you retrieve the actual object instead of just a string representation.
