max is a static method of Math. As a result, you always use it as Math.max(), rather than as a method of a Math object you create.
The following function evaluates the variables x and y:
If you pass getMax the values 10 and 20, it returns 20; if you pass it the values -10 and -20, it returns -10.
Math.min
