Cannot Pass Code Challenge - Not Sure Why

Hello. I am unable to pass the code challenge for Method Chaining. When I check my work, it says that I am wrong because I am not using the method chaining. But I am using the method chaining. My code works, I have used method chaining as required, so I'm not sure why it says I'm wrong and will not pass me through the challenge. Please help me understand what Treehouse is looking for? Thank you.

const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let displayYears;

// displayYears should be: ["2015 A.D.", "2013 A.D.", "2012 A.D."]
// Write your code below

const thisCentury = years.filter(year => year > 2000).map(year => year + " A.D.");

displayYears = thisCentury;

1 Answer

Creating thisCentury is failing the challenge and unnecessary. Just assign your filtered array directly to displayYears.

Gotcha! I got thrown off because it wanted me to create the code below the comments. Thanks, Kris! I knew it had to be something simple.
