Trying to convert a javascript object to array

Question

I have a decoded Json variable called objIntChart that looks like the following when I console.log() it.

The problem is I need it as an array that looks like this

I did a foreach loop like this in an attempt to solve it:

   var array = [];

            objIntChart.forEach(function (entry) {
                var x = 0++;
                array.push(x);
                array.x.push(entry['dateTime']);
                array.x.push(entry['entries']);

            });

However the problem is that I cannot do a push on array.x because it takes the x as the name and not the variable. Is there a solution to this?

Keep it simple:

var array = [];
objIntChart.forEach(function (entry) {
    array.push([entry['dateTime'], entry['entries']]);
});

For the record, with your approach you'd have needed array[x] = [], array[x].push(..).

Doh I am stupid. I actually did something along the lines of that first but then I just went completely off track. Anyways thanks for the response

This will do as well:

var arr = objIntChart.map(function (obj) { return [obj.dateTimes, obj.entries]});
console.log(arr);

You should use array[x] instead of array.x and also be doing array[x] = [] or array.push([]) instead of array.push(x) which will add the integer x, not an empty array, to your array.

Also, you will need to set var x = 0; outside your forloop and do x++ inside it. Currently, x will always be 1 when you use it.
