sort

The question asks: "Sort the 'saying2' array, on about line 19, so that the words are listed in length order. The shortest first. Use the 'length' property on the strings in the sort function." Any body knows how to do this?

<!DOCTYPE html> <html lang="en"> <head> <title> JavaScript Foundations: Arrays</title> <style> html { background: #FAFAFA; font-family: sans-serif; } </style> </head> <body> <h1>JavaScript Foundations</h1> <h2>Arrays: Methods Part 1</h2> <script> var saying1 = ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]; var saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"]; saying1.reverse(); saying2

You need to pass in a function as a param of sort() knowing that each string has a .length attribute you can use that in the function you pass to determine which is the longer string.

Array.sort(function(a,b){return a.length - b.length;})

Should help you get there.
