Length of Javascript Object (ie. Associative Array)
Loop through JavaScript object

var location = {
     "Steve": "New York",
     "Abigayle": "Chicago"
}

for (var i = 0; i < location .length; i++)
{
    console.log('works');
}

I’m trying to make an array, where each item has some name and value.

The code above doesn’t work. Tryed to make an object, but it doesn’t have a length property – no for loop.

location= {
     "Steve": "New York",
     "Abigayle": "Chicago"
};

Is it possible to use arrays in this context?

Answer 1

Just for reference, you can iterate over all the keys in an object:

location = {
     "Steve": "New York",
     "Abigayle": "Chicago"
};

for (var elem in location) {
    console.log(elem);
}

Produces:

Steve
Abigayle

But I think that one of the other answers is probably the correct way to what you’re looking for.
