To maintain the scope of the name variable, you can use .queue() and $.map(). It is also advisable to change the status array to an object with a property named status, which has a value of an array. This prevents any potential conflicts with this.status within the Person object.
You can also chain the .promise(/* queueName */) method to execute tasks within the .then() function once all functions in the specified queue, for example, "status", have been called and the length of the queue is equal to zero.
function Person(name, status){
this.name = name;
this.status = status;
}
var blob = new Blob(['{"stream":null}'], {type:"application/json"});
var url = URL.createObjectURL(blob);
// change `status` array reference, e.g., to `arr`
var arr = {status:[]};
var array = ["bill","bob","carl","ton"];
$(arr).queue("status", $.map(array, function(curr) {
return function(next) {
var name = curr;
// do asynchronous stuff
$.ajax({url:url, dataType:"json"})
.then(function(data) {
if(data.stream == null){
var person = new Person(name, "dead");
console.log(name, person);
arr.status.push(person);
}
})
.then(next) // call next function in `"status"` queue
}
}))
.dequeue("status")
.promise("status")
// do stuff when all functions in `"status"` queue have completed,
// `"status"` queue `.length` is `0`
.then(function() {
// `this` : `arr` as jQuery object
// `this[0].status`: array containing objects pushed to `arr.status`
console.log(this[0].status); // $(this).prop("status");
});

An alternative approach is to use $.when(), .apply(), and $.map() to achieve the same result.
function Person(name, status) {
this.name = name;
this.status = status;
}
var blob = new Blob(['{"stream":null}'], {
type: "application/json"
});
var url = URL.createObjectURL(blob);
// change `status` array reference, e.g., to `arr`
var arr = {
status: []
};
var array = ["bill", "bob", "carl", "ton"];
$.when.apply($, $.map(array, function(curr) {
var name = curr;
return $.ajax({
url: url,
dataType: "json"
})
.then(function(data) {
if (data.stream == null) {
var person = new Person(name, "dead");
console.log(name, person);
arr.status.push(person);
}
})
}))
.then(function() {
console.log(arr.status)
});
