dna	The Code uses the unshift("...") command to place items first in the list. Though it is working, a number has crept into the output from somewhere. Why is there a number at the end of the lines in the output? <html> <body> <script type="text/javascript"> var fruits = ["Banana", "Orange", "Apple", "Mango"]; document.write(fruits); document.write(fruits.unshift("Kiwi") + ""); document.write(fruits); document.write(fruits.unshift("Lemon","Pineapple") + ""); document.write(fruits); </script> </body> </html> --v -=-=- DNA

Stealth	The unshift method returns the new length of the array. You're writing it to the window. <html> <body> <script type="text/javascript"> var fruits = ["Banana", "Orange", "Apple", "Mango"]; document.write(fruits); fruits.unshift("Kiwi"); document.write(fruits); fruits.unshift("Lemon","Pineapple"); document.write(fruits); </script> </body> </html> --v -=-=- Quit posting and try Google.

dna	That's got it. The documenation should a the pertinen information about commands in one spot. It's useul to know that the function returns a value. -=-=- DNA
