Return an array that is randomly filled with string variables

Question

We have three string variables and we want a function to return an array that is randomly filled with those variables.

The desired result should be something like this:

['first string', 'third string', 'second string']; // each variable as a single element

 function generateArray(){ let a = 'first string'; let b = 'second string'; let c = 'third string'; let ourArray = []; // return ourArray randomly filled with 'a' 'b' and 'c' }

Answer 1

First, you need to put all your variables into an array then shuffles (randomly reorders) elements of that array:

  function generateArray(){

        function shuffle(array) {
            return array.sort(() => Math.random() - 0.5);
        }

        let a = 'first string';
        let b = 'second string';
        let c = 'third string';

        var localArray = new Array(a, b, c); 
        return shuffle(localArray);  

    }
