I am not sure what I am doing wrong

I am getting an error for the task.

const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let displayYears;
   displayYears = years.filter(year => year > 2000).map(filteredYear => filteredYear + " A. D. ");
app.js
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let displayYears;
   displayYears = years.filter(year => year > 2000).map(filteredYear => filteredYear + " A. D. ");

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

Hi meghana Joshi

You're on the right track and have the correct syntax.

If you have a look at the error message you are recieving: Something's not right. Output ofdisplayYears: ["2015 A. D. ","2013 A. D. ","2012 A. D. "] you'll notice that the output has a space after each period in A. D., but the instruction explicitly ask for the out to be A.D. (with no spaces).

If you just reformat your string for output to match the instructions, it will pass :thumbsup:

Remember, Challenges and the instructions are very picky and always need to be followed exactly. Even a misplaced space of period or typo will result in the Code checker throwing you a Bummer!.

Nice work, though!! :)

:dizzy:

oh ok ... thanks
