React Native to fetch from a REST API won't work because of hyphen

My fetch returns this promise which works for other fields in the API but I need to save the value for a field within that has the name "datasets-pollencheck_apiaries" however react-native inteprets the "-" as something else and I can't access this field, and continually get the error that says "Can't find variable: pollencheck_apiaries"

.then((response) => response.json())
.then((responseJson) => {
    LINK = responseJson.links.datasets-pollencheck_apiaries;

})

Any insight would be much appreciated.

This is because JavaScript thinks you're trying to do a math operation. You can also access object properties with bracket notation.

You should try this:

LINK = responseJson.links['datasets-pollencheck_apiaries']

try to change to

.then((response) => response.json())
.then((responseJson) => {
    LINK = responseJson.links["datasets-pollencheck_apiaries"];

})
