Pass args in when you call the function not when you define it

In apiRequest.js, you pass your url and apiKey into buildAPIURL function when you define the function. I'd pass these in when you call the function, so that you keep buildAPIURL generic

e.g.

const buildAPIURL = ( date, apiURL, apiKey ) => {
  return `${apiURL}?api-key=${apiKey}&begin_date=${date}&end_date=${date}&sort=newest`;
}
