JSON and JavaScript - how to read my list by using json

I don't know why I can not read object by using below way

function loadData(){
    $.getJSON('data.json', function(data) {
        $.each(data, function(Index, entry) {
            mem = new user(entry.name, entry.age, entry.location);
            userList.push(mem);
        });
    });
    return false;
}

function fillTable(){
    var html = "";
    console.log(userList);
    console.log(userList[0].name);
    $.each(userList,function(index , user){
       console.log(index);
        html += '<tr>';
        html +=  '<th>'+this.name+'</th>';
        html +=  '<th>'+this.age+'</th>';
        html +=  '<th>'+this.loca+'</th>';
        html += '</tr>'

        console.log(this.name);
    });
    $("#listTable").html(html);
}

   function loadData(){
        $.getJSON('data.json', function(data) {
            $.each(data, function(Index, entry) {
                mem = new user(entry.name, entry.age, entry.location);
                userList.push(mem);
            });
      fillTable()
        });

        return false;
    }      

   function fillTable(){
        var html = "";
        console.log(userList);
        console.log(userList[0].name);
        var self = this;
        $.each(userList,function(index , user){
           console.log(index);
            html += '<tr>';
            html +=  '<th>'+self.name+'</th>';
            html +=  '<th>'+self.age+'</th>';
            html +=  '<th>'+self.loca+'</th>';
            html += '</tr>'

            console.log(self.name);
        });

}

this will point to inside function, you need to delcare this outside this in outside function.

Try this it may work

Call fillTable in loadData function, as getJson is async

function loadData(){
            $.getJSON('data.json', function(data) {
                $.each(data, function(Index, entry) {
                    mem = new user(entry.name, entry.age, entry.location);
                    userList.push(mem);
                });
fillTable(); -- call it here
            });

            return false;
        }
