How do I loop through a JSON array?

I have a Discord.js bot, I wanted to make a lockdown command, but my channel ids are stored in a JSON file, and I dont know how to iterate through it. This is the JSON configuration:

{
    "channels": {
        "main": {
            "id": "691548147922763825"
        },
        "creations": {
            "id": "700390086390448148"
        },
        "fanart": {
            "id": "691551615873843211"
        },
        "memes": {
            "id": "691549417173680148"
        }
    }
}

How can I loop through it? I know that just doing forEach on a JSON file doesnt work, so I need some help.

You can use for..in loops on objects to get the keys and iterate over them. Objects don't implement the Iterable interface, so for...of doesnt work. And forEach is not a method on an object, but on an array.

const json = {
    "channels": {
        "main": {
            "id": "691548147922763825"
        },
        "creations": {
            "id": "700390086390448148"
        },
        "fanart": {
            "id": "691551615873843211"
        },
        "memes": {
            "id": "691549417173680148"
        }
    }
}

for( let key in json.channels ) {
  console.log( key, json.channels[key] )
}
