please guys, is there any advantage of || over ?? . I see that ?? solves some of the problems that || can not solve
?? is newer so there’s a higher chance it’s unsupported on your user’s browser.
They function differently, so I don’t think you can really make a direct comparison. If I’m checking that something is undefined or null, I would prefer ?? over ||.
The advantage is that is selects differently. If null and undefined are the only falsy values you care about, you use that.
const count = 0
const response1 = count || undefined
const response2 = count ?? undefined
Is 0 a valid count? The first one thinks it isn’t, the second one thinks it is.
Use || unless ?? is specifically what you want.
Yes, there could be compatibility issues with NCOs, but that is what babel is for.
