This has to be a bug, right? The following code isn't passing the challenge:
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20 = years.filter(year => year >= 2000);

const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20;
// century20 should be: [1989, 2000, 1999, 1973]
// Write your code below
century20 = //...

My answer:
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20;
century20 = years.filter( year => year.toString().slice(0, 2) == '19'|| year == 2000 )

Full Stack JavaScript Techdegree Student 6,852 PointsAbsolute simplest solution for this particular array:
century20 = years.filter(year => year < 2001)

28,330 PointsI'm getting the same error. Strange. Your code is actually filtering for years in the 21st Century (year >= 2000), but it still doesn't work when I changed it to filter for 20th Century years. This still breaks and returns the "" error:
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20 = years.filter(year => year <= 2000);

50,144 PointsYup, doing so passes the challenge. It's just personally annoying to me to not modify the variable declaration to include the filter since it's a bit more succinct.

Full Stack JavaScript Techdegree Student 13,897 Pointssimplest solution is to use the && operator.
century20 = years.filter(year => year>= 1900 && year<=2000)

Full Stack JavaScript Techdegree Student 13,897 Pointsthe expected answer is years less than 2000. Your solution is correct, but you are searching years greater than 2000
