Can't find the problem, why my code doesn't work

Don't understand what is the problem

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

// century20 should be: [1989, 2000, 1999, 1973]
// Write your code below
century20 = years.filter(year => year < 2001 && year > 1899);

The error you receive is "Bummer: It looks like you changed or removed the provided code. You can hit "Restart" if you want to start over."

The checker doesn't like that you changed this line

let century20;

Change it back and you'll pass

You have modified the "century20" variable to an empty array. Just declare the variable and afterward reassign the variable with the expression. Try this will work 100%:

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

// century20 should be: [1989, 2000, 1999, 1973]
// Write your code below
century20 = years.filter(year => year >= 1900 && ( year <= 2000));
