JavaScript JavaScript Array Iteration Methods Array Manipulation Practice filter()

Need some help;

Using the filter method on the years array, return an array of only the years in the twentieth century (remember: the twentieth century includes the year "2000"). See the comments for the correct result. Store the new array in the variable century20.

app.js 
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20 = years.filter(years => % 1 === 0);

// century20 should be: [1989, 2000, 1999, 1973]
// Write your code below

Hi Humoyunmirzo Nosirov, First, get rid of '%'. Second, you're implementation of the condition is wrong.

Should be like so:

let century20 = years.filter(year =>  year <= 2000);
  • Less than but equal to 2000
  • Also year(singular) instead of years(plural) wich get confused with the array itself
