Tharun Here is the solution : Code : const array = [ /*your array */ ]; const randomIndex = Math.floor(Math.random() * array.length); const randomElem = array[randomIndex]; console.log(randomElem); Here is a demo : https://code.sololearn.com/W54yd8ILd5AT/?ref=app

May I know how this is not working. I want random element to go on a loop continuously let Array =[ "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "2", "2", "2", "2", "2", "2", "2", "2", "2", "2", "2", "2", "2", "2", "5", "5", "5", "5", "5", "5", "5", "10", "10", "10", "10", "2roll", "2roll", "2roll", "chance", "chance", "4roll", ] var t = 0; var i = 10; const randomIndex = Math.floor(Math.random() * Array.length); const randomElem = Array[randomIndex]; console.log(randomElem); for (var element of randomElem ) { if(element ===1) { t = t + i; console.log(element ) console.log(t) console.log(i) } else { t = t - i; i = i * 2; console.log(element ) console.log(t) console.log(i) } }
