    }
  });
  
  function isOdd(num) {
    return num % 2 === 1;

Tests:

underscore
var result = _.chain(data) .map(item => item.counter) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
native js
var result = data.map(item => item.counter) .filter(isOdd) .map(square) .filter(lessThanThreeDigits)
