[Solved-5 Solutions] Generate random number between two numbers in JavaScript - javascript tutorial
Problem:
How to generate a random number in JavaScript ?
Solution 1:
If we need to get the numbers between 1 and 10, we would calculate:
Math.floor(Math.random() * 10) + 1
Where,
- 1 is the starting number
- 10 is the number of possible results (1 + start (10) - end (1))
Solution 2:
Random intervals to be allowed that do not start with 1.
function randomIntFromInterval(min,max)
{
return Math.floor(Math.random()*(max-min+1)+min);
}Solution 3:
This is one of the solution:
(Math.random() * 6 | 0) + 1

if (min < 0) {
return min + Math.random() * (Math.abs(min)+max);
}else {
return min + Math.random() * max;
}
