How to randomly select an array out of several in JavaScript

Question

I have three arrays with 2 strings each, and would like to randomly select one of the arrays.

array1 = ["hello", "world"];
array2 = ["all", "good"];
array3 = ["bye", "now"];

Something like collecting the three arrays into one, and then math.random? I'm working with JsPsych, in case it is relevant

Add your arrays to another array, then use the answers from [Getting a random value from a JavaScript array](https://stackoverflow.com/q/4550505/215552) — Heretic Monkey, Mar 31 '21 at 12:08

To combine arrays with each other, you can use the method contact().

For example :

var test1 = ['Emil', 'Tobias'];
var test2 = ['Arthur', 'Simon'];
var array = test1.concat(test2);

For generate a random value, read this topic : Getting a random value from a JavaScript array

Thank you! Still, this is choosing strings form both variables at once eg. I'm getting Emil and Simon – jseabra Mar 31 '21 at 12:36
