Selecting a Random Object Property in JavaScript

The Problem

You may be trying to grab information from a randomly selected object, but the code may not function as desired if the logic isn't set up properly. Specifically, if you define a random variable but it does not reference existing properties correctly, this can lead to issues. Let's look at a typical situation that may cause confusion:

Example Code Snippet

You may have started with something like this:

In this scenario, calling PK[PKS].number won’t work as intended because PK[PKS] gives you the string (like "Random1") and not the object you're expecting.

The Solution

Instead, the solution involves organizing your objects into an array. This allows you to find the random object based on the name derived from your initial random selection. Here’s how to implement this correctly.

Step-by-Step Breakdown

Create an Array for Storing Objects:

Instead of creating separate variables for each random object, put them in an array.

Generate a Random Index:

Find the Object:

Use the find() method to locate the object that has the matching name with the selected string.

Updated Code Implementation

Here's how the final code would look after these adjustments:

Explanation of the Code

Array of Names and Objects: The PK array holds string names, while the randoms array holds objects with properties of name and number.

Sending the Output: Finally, if findRandom is successful, it sends the corresponding number back to the chat.
