Get Data from JSON file using a variable (JS/Discord.js)

Question

I was working on my discord bot when suddenly this problem occurred.

Usually, once you link a JSON file, you can get data by doing jsonFile.path to get some form of information.

I ran into a problem where I want to replace path with a variable's value.

Is there anyway that I could do this? In my case I am using a command randomly generate a number, check if that number is currently on the file, add it to the JSON file.

How are you "linking" the JSON file? Are you using any external library? How are you writing the file? — Federico Grandi, Aug 27 '18 at 19:16
Oh sorry I forgot that this, I figured out. A friend showed me. Thanks for your concern! — NintendoZaedus, Aug 27 '18 at 20:40

So I figured this out awhile ago, and I forgot to put an answer but anyways this is how I can find information from an object path using a variable. Pretty much you can get information from a JSON object by doing the following

let object = {“name”: “John”}
let path = “name”;
console.log(object[path])
