The first question use the .reverse() method which you attach to the array itself.

The second question uses the .sort() method which has a basic format like this:

myArray.sort(function(a,b) {
   //comparison between a and b in here
  // return <0, 0 or >0
});

The function you supply inside the .sort() method is used to compare elements in an array. In this example, a represents one element in an array and b represents the next element in the array. The function needs to return one of three values:

1. a number LESS THAN 0
2. the number 0
3. a number greater than 0

• If the number is LESS than 0, then a is sorted BEFORE b

• If the number is 0, then a and b stay in the same spot in relation to each other

• If the number is GREATER than 0, then b is placed BEFORE a

For this Code Challenge, you need to compare the lengths of strings in an array. You can get the length of a string with the .length property. You can use some simple math to get the proper return value for the .sort() function:

a.length - b.length;

• If the string a is shorter than b then the answer is less than 0 (so a will go before b).

• If the string a is longer than b then the answer is greater than 0 (so b will go before a).

• If the string a is the same length as b then the answer is 0 (so they stay in the same position`).

Hope these hints help.
