  var number = Math.min（Math.max（parseInt（number），1），20）; 
 

I want to limit a number between two values, I know that in PHP you can do this:

$number = min(max(intval($number), 1), 20);
// this will make $number 1 if it's lower than 1, and 20 if it's higher than 20

How can I do this in javascript, without having to write multiple if statements and stuff like that? Thanks.

like this

var number = Math.min(Math.max(parseInt(number), 1), 20);
