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

We use charAt() to get a specified index in a string. We don't have any string in our array. Also no need to push into a new variable. The challenge asks to store in century20.
So you just have to return to the years that come in the twentieth century. So our condition will return all years less than equal to 2000.
Like this:
century20 = years.filter(year => year <= 2000);
