Generate random number between two numbers in JavaScript



Is there a way to generate a random number in a specified range (e.g. from 1 to 6: 1, 2, 3, 4, 5, or 6) in JavaScript?


Answer




Important



The following code works only if the minimum value is 1. It does not work for minimum values other than 1.



If you wanted to get a random integer between 1 (and only 1) and 6, you would calculate:



Math.floor(Math.random() * 6) + 1  


Where:





  • 1 is the start number

  • 6 is the number of possible results (1 + start (6) - end (1))
