How to format currency symbol in Intl.NumberFormat?

Question

In a JSON data, I've certain currency data values in the form as follows:

const currencyData = [
    {
      "₹": "INR"
    },
    {
      "¥": "JPY"
    },
    {
      "€": "EUR"
    },
    {
      "£": "GBP"
    }
  ];

I've created a function which accepts 2 parameters one for 'amount' and other for 'currency code', but, what could be done, when second parameter is "$" or "¥" i.e a currency symbol. My intention is to map the currency symbol with above JSON data and give the relevant output, like for e.g: "$" is passed then it should filter comparing with the above JSON data and pass "USD" output and then it can be passed in the below function

const currencyFormatterNew = (amount, currCode) => {
    let currencyCode;
    try {
      if (currCode == "undefined" || currCode == "") {
        currencyCode = "";
      } else {
        currencyCode = currCode;
        return new Intl.NumberFormat("en-US", {
          style: "currency",
          currency: currencyCode,
          minimumFractionDigits: 0
        }).format(amount);
      }
    } catch (err) {
      console.log(err);
    }
  };

The function is called as following: {currencyFormatterNew(10000, "JPY")}

What would be optimal solution to map the 'currency symbol' with above json data and then give required output which could be used in the function created?

Answer 1

  const getCurrencyCode = (code) => {
    const k = currencyData.find(a => Object.keys(a) == code);
    return Object.entries(k)[0][1];
  }  

you can try this. If you want to you can change the last return statement as following

 return Object.values(k);  // it will return an array
