如何获取给定货币字符串（“GBP”、“USD”等）的货币符号？我想出的最好的似乎冗长可笑，还有其他方法还是我最好使用查找表？
const userLocale = "EN-gb";
const userCurrency = "GBP";
const withValueEl = document.querySelector(".withValue");
const withoutValueEl = document.querySelector(".withoutValue");
const valueWithCurrency = Number(0).toLocaleString(userLocale, {
style: "currency",
currency: userCurrency,
minimumFractionDigits: 2
});
const valueWithoutCurrency = valueWithCurrency.replace(Number(0).toLocaleString(userLocale, {
minimumFractionDigits: 2
}), "")
withValueEl.innerHTML = valueWithCurrency
withoutValueEl.innerHTML = valueWithoutCurrencyWith value:<span class="withValue"></span><br /> Without value:<span class="withoutValue"></span><br />
