Collection problem

Is there any easy way to modify an array that is placed as a value in an Collection object?

Im thinking about doing this:

const { Collection } = require("discord.js");
const collection = new Collection();
collection.set("xyz", ["1", "2", "3"]);

const query = "xyz";
const array = collection.get(query); // ["1", "2", "3"]
array.push("4");
collection.set(query, array);

const { Collection } = require("discord.js");
const collection = new Collection();
collection.set("xyz", ["1", "2", "3"]);

const query = "xyz";
const array = collection.get(query); // ["1", "2", "3"]
array.push("4");
collection.set(query, array);

but in an easier way

You don't have to set() the key to the "new" value Arrays are just pointers in JS, so if you modify an array in one place, it modifies the array elsewhere too since both the array you modified and the array currently in the collection both point to the exact same memory address Other than that, you're doing it in the easiest way possible You could combine all of it into one line collection.get("xyz").push("4") but that isn't really changing anything under the hood

thank you! One more question, would collection.get("xyz")["array"].push("4") work too?
