// create an array of integers

var integers = new Array( 3, 8, 1, 9, 7, 5, 4, 2, 6 ); 

// sort the integer array numerically

integers.sort();

// create an array of floating-point numbers

var floats = new Array( 0.5, 0.125, 0.75, 0.25 ); 

// sort the floats array numerically

floats.sort();

// create an array of strings 

var strings = new Array( "Michael", "Andrew", "David" ); 

// sort the strings array alphabetically

strings.sort();

// separate the elements with a hyphen

var str = "Integers array: " + integers.join(" - ");
str += "\nFloats array: " + floats.join(" - ");
str += "\nStrings array: " + strings.join(" - ");

// display all three sorted arrays

alert( str );
