This is also a very nice solution. I’ll add it to the tips! Thank you. I know that for some people, regex can be a eyesore. But there is beauty in its power.

Not much difference but I like to use sets for these comparisons for faster lookups.

const localDomains = new Set([...])
localDomains.has(...)
