Closed last year.

In an example like this, I'm trying to get inside the array of the 'new folder' to take out the keys from the information array that is nested inside the "new folder' array.

    let info = [
    {
    	fileName: ‘new folder’,
    	size: 233423,
    	information:
	{ 
	       created: ‘2014-06-06’,
	       modified: ‘2016-03-04

	}
    },
    {
    	fileName: ‘untitled’,
    	size: 554,
    	information: 
	{
	      where: ‘desktop’
	  
	}
    },
    {
    	fileName: ‘documents’,
    	size: 743482,
    	information: ‘created yesterday‘
	
    }

For now I tried

console.log(info[0].information)

It does the trick but I was wondering if there was another way to do it?

I also was trying to get the 'modified' key of the 'new folder' array with

console.log(info[0].information.modified)

which again worked, but I don't know if this would seem as hard coding?
