Remove one level of nested arrays from JS data structure

Question

How can I convert the following data structure:

var data = [ [ { time: 1, speed : 20 } ] ];

to

var data = [ { time: 1, speed: 54 } ];

I just want to remove the array.

20

As the data is an array, you just want to select the first element of the outer array

so the solution would be

var data = [[{time:1,speed:20}]]; // Or whatever the data is
data = data[0];

Or if you're accessing the data via another object

var data = yourObject[0];

Try this :

JSON.stringify(data).substr(1,JSON.stringify(data).length-2);
