Delay between API calls Node.js

Question

I have a jquery $.each loop feeding a different variable to a POST API call. I am trying to delay the API calls between each variable say 5 seconds, but it is executing all at the same time even with the setTimeout.

var skuList = require('../inputSKU.json');

const url = www.someurl.com

const query = `query example xyz`

//the problem below

$.each(skuList.list, function getData(i, e) {
  var variables = e;
  
  var body = JSON.stringify({
    query,
    variables
  })
  var resJSON = '';
  var a = '';

  setTimeout(async () => {
    var res = await fetch(url,
      {
        method: 'POST',
        body: body,
        headers: {
          'Content-Type': 'application/json',
          'Content-Length': body.length,
          "Accept": "application/json",
          'x-gql-access-token': '8635be91-b771-11ed-aa31-49d35f4239b3',
          'x-gql-country': 'US'
        }
      }
    )

    a = await res.json();

    resJSON = a.data;

    console.log(resJSON)

  }, 5000);
});

This will rapid fire console.log the resJSON. Is there an elegant solution to adding the delay?

Seems there is a solution if I was using a for loop with an index.

for(var i in list) { // list is an array, i is current index
  setTimeout(function() {
    apicall()
  }, 1500 * i) // With each iteration, the delay increases
}

Perhaps something like this for the $.each?
