Need help in accessing array of array objects

Please find the attached image.
I retrieve an array dynamically named ‘details’ , which has array of objects which in turn has array of objects, as shown in pic.
I should access the elements ‘date’. and ‘ctr’ from each of these arrays and prepare a new array.
I tried details[0]. It fetched the array of objects in 0th position . It is shown in console log as ‘details 0’
Now if I try with ‘details[0][0][0].date’ in order to access the date element, its giving out error as ‘undefined’
I tried by various means like details[0][0] also. But I couldn’t figure out how to navigate these array of objects. Please help me how can I access the elements.

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
