Can't get filtering right, but I feel like I'm close!

The years.filter is definitely in the wrong place, but I'm not sure where I should put it.

app.js 
const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012];
let century20;

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

function pushToArray(years.filter, year => {
  if (year <= 2000) {
    century20.push(year);
  }
}));

century20 = years.filter( year => year <= 2000 );
console.log(century20);

So they want you to have the century20 variable to be the return value of years.filter.

let century20 = years.filter(year => {
***conditional****
});

filter is a built in array function. If you want more info this is a great video on higher array functions. ----> https://www.youtube.com/watch?v=rRgD1yVwIvE
