Hello everybody. That's my first code using JS. How can I pick a random value from an array with string values?

This way var s=["hello","spam","eggs"] var a=s.length; var b=Math.floor(Math.random()*a); console.log(s[b]);

function random(arr){ return arr[Math.floor(Math.random()*arr.length)]; } var myArr= ["a" , "b" , "c"]; console.log(random(myArr));
