Random Number Function code Problem

Hello Everyone,

Why does my code below not produce an alert box with a random number?

randomrange(x,y) {

var randnum = Math.floor(Math.random() * (x - y + 1)) + y;

return randnum;

}

alert(randomrange(1,6));

There are few issue in your code -

  1. use the 'function' keyword i,e function randomrange(x,y){ .... }
  2. You always subtract a lower value from higher value and add the lower value . So , you should use :
    var randnum = Math.floor(Math.random() * (y - x + 1)) + x;
    Finally , your code should look like this :
function randomrange(x,y){
var randnum = Math.floor(Math.random() * (y - x + 1)) + x;
return randnum;
}
alert(randomrange(1,6))
