Getting return of nested function

I am trying to get the value from a currency converter API, unfortunatley the way the data is brought in the value I want is within nested objects. to get around this I found a function which breaks down the nesting to get the valuer I want back

// Breaks down object nesting to access const getNestedObject = (nestedObj, pathArr) => { return pathArr.reduce((obj, key) => (obj && obj[key] !== 'undefined') ? obj[key] : undefined, nestedObj); }

So I have a function to get the value of the transfer rate, it is printing the correct values to the console but it is returning undefined. I'm sure it has something to do with the function nesting but I can't work it out.

// Gets current transfer rate from API function $getTransferRate(currency1, currency2){ const transferSelector = currency1+"_"+currency2; console.log(transferSelector); $.get( "https://free.currencyconverterapi.com/api/v6/convert?q="+transferSelector , function( data ) { const transfer = getNestedObject(data.results, [transferSelector, 'val']); console.log(transfer); return transfer; }); }
