JavaScript JavaScript Array Iteration Methods Array Manipulation Practice filter()

can Anyone help me , please

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.

Give it your best "good faith" try, at least doing the parts you can, then post your code here and we can help you from there.

const years = [1989, 2015, 2000, 1999, 2013, 1973, 2012]; let century20 = years.filter(year => year <= 2000);

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

Hey, that's pretty good, and you're very close!

But while it would technically work, it can confuse the challenge if you modify the code provided. Put all your code below the line that says "Write your code below". And since the variable is already declared, you can leave off the "let".

Also, you have an extra comparison that is not needed. So instead of "year => year <= 2000" you can just write "year <= 2000",
