JavaScript JavaScript Foundations Arrays Methods: Part 2

Stuck on task 2

Task 2 in this challenge asks to sort an array of strings by length, using the "length" property on the strings. I can't figure out how to make parameters for my function in the "sort" method using the "length" property. I'm not even sure I'm properly applying the "length" property to the strings in my array.

Thanks in advance for help.

Hi Jerilyn,

I'm haven't seen the task, but sorting an array by string length in JS can be done as followed:

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

where arr is the name of your array.

Hey Jerilyn,

Could you post the current code that you are currently using?

The code that Sjors posted (when implemented correctly) will allow you to complete this challenge. However, if we approach this issue by first looking at your code I feel that you will learn a lot more.

Thanks, Calvin
