I was also wondering what's the difference between those two and I've found it. Nullish Coalescing better handles cases when it comes to truthy/falsy values.
For example:
const a = 0
const b = a || 100
console.log(b) // 100
Same thing, but different result with Nullish Coalescing:
const a = 0
const b = a ?? 100
console.log(b) // 0
I personally hate the use of the || operator in this context, but that's mostly because my background is a C# one where I read the operator and think that b would be assigned to true since a and 100 would both be evaluated as booleans.
Obviously they wouldn't, but to me ?? is way more intuitive than the use of || in this context.

I thought I remembered something like this being the edge case where this was useful... Thank you, this seems like a better example!
