TS 3.7 Release Notes Nullish Coalescing example wrong

I know this was only given as an example, but there's a small mistake:

What is wrong?

It says that let volume = localStorage.volume || 0.5 will be 0.5 when localStorage.volume is set to 0, but everything stored in localStorage can only be a string and "0" is truthy.

localStorage.volume = 0; // saved as "0"
let volume = localStorage.volume || 0.5;  // volume = "0" || 0.5
volume === "0" // Not 0.5 as mentioned in the example
