Question 297944 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – Why I have run the random function code in shorter form and it is not working?

I have try to make the random number for code in this form using snippet in chrome

var n = Math.random();
n = n * 6;
Math.floor(n) + 1;

but when i try to make it shorter like this

var n = Math.floor(Math.random() * 6) + 1;

seem like it won’t work for me (undefined), but again I have seperated like this

var n = Math.random();
n = Math.floor(n * 6) + 1;

It kinda work. What is the problem of the shorter form for this code?

    Welcome to stackoverflow.
    Please try to add put your code in the code snippet element.

    Like this:

    var n = Math.random();
n = n * 6;
n = Math.floor(n) + 1;

console.log(n);

    And here your second code:

    var n = Math.floor(Math.random() * 6) + 1;
console.log(n);

    As you can see, both are working like expected.
