Passing parameters to a callback function using arrow function

You can do that:

const fetchItems = (callback, ...params) => {
    //Do whatever you want with the params
    callback(response);
}

Example of usage:

const fetchItems = (callback, ...params) => {
    callback(params);
}
    
fetchItems (console.log, 'foo', 1);

More of less you can do it the same way

const getCountries = (data, callback) => {
    //After ajax success
    callback(response);
}

getCountries("data", ()=>{});
