how to filter not 20th centuries from the years array

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

century20 = years.filter(t => { if (t === '1989' && t === '1999') { return true } }) console.log(century20)

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

Hi srinivas gudimella! You can use the filter method of an array, like this:

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

console.log(years.filter(year => year <= 2000));
//expected output from console: [1989, 2000, 1999, 1973]

Hope this helps! Happy coding!
