Create an Array with a dynamic name derived from the values of other variables

In my JavaScript project, I am facing a challenge in naming arrays based on dynamic data such as room numbers and user IDs. As the rooms and users are constantly changing, I need to create multiple arrays accordingly.

Although this code is incorrect, it showcases what I want to achieve:

var room + userId = new [];

How can I implement this functionality in JavaScript, especially considering that this is for the back-end development rather than client-side browser work?

Answer №1

It is simply impossible.

During my own investigation, I discovered that this goes against the intended usage of the language.

The best workaround is to utilize key-value pairs like so:

var collection = [];
collection[room + userId] = [];
