What is the reason behind labeling the final element as "remove"?

Just starting out with django.

Currently working on using a json in my javascript:

views.py:
a = ModelA.objects.filter(status = 'A').values('name', 'id', 'pos', 'status')
b = ModelA.objects.filter(status = 'B').values('name', 'id', 'pos', 'status')
data = {
    'a': a,
    'b': b,
}
return HttpResponse(simplejson.dumps(data), mimetype='application/json')

Exploring nodeshot, where I found a function to fetch json data:

$.getJSON(nodeshot.url.index+"nodes.json", function(data) {
        nodeshot.nodes = data;
    });

However, when trying this:

var data = nodeshot.nodes[status];         //'a' for example
for(var node in data) {
...
}

Upon using alert(node), the output is:

0
1
remove

The unexpected value "remove" in the loop results raises questions. This loop should only iterate twice.

Answer №1

When looping through the list object, it's important to consider that the property names may include both element indexes and the names of enumerable functions.

Instead of iterating using a for...in loop, treat the list like an array.

Update your code by replacing:

for(var node in data) {

with:

for(var i=0; i<data.length; i++) {
   var node=data[i];
