My apology for giving you incorrect Javascript code.  I corrected my code.
Here it is:

function Setup() {
    var XMLHttp;
    var JSON_Data;


    XMLHttp = new XMLHttpRequest();
    XMLHttp.open("GET", "
http://localhost:8080/exist/rest/db/apps/HTML_Student/people.json", true);
    XMLHttp.onreadystatechange = function () {
         if(XMLHttp.readyState == 4){}{
             JSON_Data = XMLHttp.responseText;
             document.getElementById("JSON_Text").value = JSON_Data;
         }

    };

}

When I run the code and check the console, it states that it can't find
people.json.  I don't know why my webpage can't find people.json  Can you
assist me?
