How do I use "contain" if there are two true options?

[ReaderGuy42]

In my frontmatter there is a variable called Country: which is followed by the two letter code for that country, so e.g. Country: UK for the United Kingdom.
Now I'd like Dataview to replace this country code with a flag emoji in my Cards table, which I do with this rather unwieldy chain of choice combined with contain:

choice(contains(country, "US"), " 🇺🇸 ", 
choice(contains(country, "UK"), " 🇬🇧 ", 
choice(contains(country, "JP"), " 🇯🇵 ", 
choice(contains(country, "IN"), " 🇮🇳 ",
choice(contains(country, "CA"), " 🇨🇦 ",
choice(contains(country, "CL"), " 🇨🇱 ",
choice(contains(country, "IT"), " 🇮🇹 ",
choice(contains(country, "SI"), " 🇸🇮 ",
choice(contains(country, "AR"), " 🇦🇷 ",
choice(contains(country, "DE"), " 🇩🇪 ",
choice(contains(country, "AT"), " 🇦🇹 ",
choice(contains(country, "PL"), " 🇵🇱 ",
choice(contains(country, "MY"), " 🇲🇾 ",
choice(contains(country, "FR"), " 🇫🇷 ",
choice(contains(country, "CN"), " 🇨🇳 ",
choice(contains(country, "NG"), " 🇳🇬 ",
choice(contains(country, "KE"), " 🇰🇪 ",
choice(contains(country, "AU"), " 🇦🇺 ",
choice(contains(country, "BD"), " 🇧🇩 ",
choice(contains(country, "NZ"), " 🇳🇿 ",
choice(contains(country, "HK"), " 🇭🇰 ",
choice(contains(country, "SP"), " 🇪🇸 ", "")))))))))))))))))))))) as Flag

However, for some cases TWO countries apply, such as when a movie is made by people from different nations. How do I implement this? It would look like Country: US, UK. But since my chain of choice has US first, only the US flag shows up. How do I combine these so both flags would show up?

Thanks!

BTW if someone knows of a more elegant way of doing this, I'm all ears :)

I can suggest this, but isn't easy to understand it (don't ask me to explain this "IIFE = immediately invoked function expression"..., I'm not a coder or similar, just a curious):

TABLE split(Country, ", ") AS Country, map(split(Country, ", "), (c) => ((x) => {US: "🇺🇸", UK: "🇬🇧", FR: "🇫🇷", PT: "🇵🇹"}[x])(c)) AS Flag
WHERE Country
SORT file.name ASC

• Country: US, UK isn't the right syntax to a list of values. US, UK is just a string with a comma. That's why you need to use the split() function, with the advantage that the results of this operation are arrays (even if only one value).
• about the ((x) => { A: 1, B: 2 }[x])(Field), well, don't ask me :) - link
