JScript: Take as input an array of strings, return new array containing only strings with fewer than five characters

Question

function fiveChar(inputArray) {
    var output = input.join();
    return output;
}

console.log(fiveChar(['lion', 'gorilla', 'elk', 'kangaroo']));

How can I make this only return lion and elk, given they're under five characters?

Thanks!

@raisesHand `filter` is a looping mechanism. But yes you can manually achieve this using `for`. Create dummy array and push necessary element in it and return it — Rajesh, Oct 21 '16 at 13:18
@raisesHand: Yes. You write a loop, and do the comparison inside it, pushing to a new array for the ones that you want to keep. But if that caveat was important, it needed to be in the question. — T.J. Crowder, Oct 21 '16 at 13:19

You can use .filter() to filter the array down into a new array with strings that have a .length less than 6 characters.

function fiveChar(inputArray) {
  return inputArray.filter(function(in) { 
    return in.length < 6;
  });
}

We don't need *yet another* answer to "How do I filter an array?" – T.J. Crowder Oct 21 '16 at 13:18
