Determine Minimum and Maximum

If you want to compare two numbers in Java Script, you can always use an if-else statement, but the Math object provides two methods that do that for you. The Math.max method returns the highest value, the Math.min method returns the lowest value.

var a = 5;
var b = 6;
var n = Math.max(a,b);

The code shown above declares two variables a, assigned as value of 5, and b, assigned as value of 6. When both variables are passed to Math.max method, it returns the value of the variable with the highest value (6).

var a = 5;
var b = 6;
var n = Math.min(a,b);

Similarly, When both variables are passed to Math.min method, it returns the value of the variable with the lowest value (5).

When you need to compare two numbers use the apropriate Java Script Math object max or min method.
