// create and initialize a new array

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

// get elements #2 up to #4

var str = "Slice A: " + nums.slice( 2, 4 ) + "\n";

// get elements #1 to one before the final element

str += "Slice B: " + nums.slice( 1, -1 ) + "\n";

// get elements #3 to end

str += "Slice C: " + nums.slice( 3 ) + "\n";

// display all three slices

alert(str);
