A new javascript question, again, and again...

(Updated)

a is a string where I input a word, it will then be sent to a Dictionary API and do the fetchApi(). After getting the result, if a matches the result[0].word, it will trigger the function Func1(), if not then it will trigger the other function Func2().

What I'd like to ask is there any way to use setInterval() for the function data(result), after deleting the part .then(result => data(result)) in the function fetchApi(a)? Or can I only put setInterval() for both functions Func1() and Func2()?

Thank you very much!

var a = "";

function fetchApi(a) {
  let url = `${url}${a}`;
  fetch(url).then(res => res.json()).then(result => data(result));
  }

function data(result) {
  // console.log(result);
  if (a == result) {
    Func1();
  } else {
    Func2();
  }
}
