How do you get value from multidimential object when name path is stored in array of unknown length?

I’m creating a folder directory and need to allow users to navigate within it. I have a global variable that stores their location in the directory. How can I access the content within their selected folder.

This is what I what.

let location = ["2022","March","Week4"];
let content = folderInformation["2022"]["March"]["Week4"];

However, the file names "2022, March, Week4, ect" are set by the user.

So I could do this.

let location = ["2022","March","Week4"];
let layer1 = location[0];
let layer2 = location[1];
let layer3 = location[2];
let content = folderInformation[layer1][layer2][layer3];

However, the user could be 2 layers deep or 15.

I tried

let layers = location.join("][");
let content = folderInformation[layers];

and

let layers = "["+location.join("][")+"]";
let content = folderInformation+layers;

with no success. What is the best option to access the content within the object?

>Solution :

A short version with reduce:

const content = location.reduce((o,l)=>o?.[l],folderinformation);
