  function isOdd(num) {

Tests:

Lodash
var result = lodash.chain(data) .map(function(m) {return m.counter;}) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
Ramda without relying on currying or composition
var result = R.filter(lessThanThreeDigits, R.map(square, R.filter(isOdd, R.pluck('counter', data))));
Ramda with currying and composition
var result = R.pipe( R.pluck('counter'), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Underscore
var result = _.chain(data) .map(function(item) {return item.counter;}) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
Vanilla v1
var result = data.map(function(x) {return x.counter}) .filter(isOdd) .map(square) .filter(lessThanThreeDigits)
vanilla v2
var result = []; for (var i = 0, len = data.length; i < len; i++) { if (isOdd(data[i].counter)){ var r = square(data[i].counter); if (lessThanThreeDigits(r)) { result.push(r); } } }
