Generate random number between two numbers in JavaScript

random-number.js

function randomIntFromInterval(min,max){
    return Math.floor(Math.random()*(max-min+1)+min);
}

Is it possible to have like a test case for this one to ensure that it doesn't return a number below min and over max?

@lourdrivera123 you do not need a "test case" for this situation because the "algorithm" does not return values greater than minimum and maximum. For more explanation about it you can read the mozilla guide.

But if you really want to, you can do something like that:

    function randomIntFromInterval(min,max){
        let result =  Math.floor(Math.random()*(max-min+1)+min);
        if(result < min){
            result = min;
        }
        else if(result > max){
            result = max;
        }
        console.log(result);
    }

Again, you don't need to check this function, because you pass the min/max. On the mozilla guide, for the Math.random, you can find other random generator's.

function Numbers(min,max){
console.log(Math.floor(Math.random()*(max-min+1)+min));
}
Numbers(15, 20)

Thanks it´s working good 👍
