Can i use map to remove empty cells from array without using filter

const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2];

const squareList = (arr) => {

"use strict";

// change code below this line

const squaredIntegers = => (num=>0 && num%2===0)?num*num:[]);

// change code above this line

return squaredIntegers;


// test your code

const squaredIntegers = squareList(realNumberArray);


I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.


No you can’t , map always returns the exact number of elements of your input array , so if you want to be selective on the output array, have to use filter or , a for loop or forEach , like:

let output=[]
arr.forEach(num => {
  if (num>=0 && num%2===0) output.push(num*num)
return output

FYI, you have a syntax error/typo num=>0 should be num>=0 otherwise your map will return functions for elements in the output array since => is reserved
