Script Preparation code:

var data = _.range(10000).map(function(i) {
  return {
    counter: i
  }
});

function isOdd({ counter }) {
  return counter % 2 === 1;
}

function square({ counter }) {
  return counter * counter;
}

function lessThanThreeDigits(value) {
  return value.toString().length < 3;
}

Tests:

Lodash
var result = _.chain(data) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
Ramda compose
var result = R.compose( R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Ramda pipe
var result = R.pipe( R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Immutable List
var result = Immutable.List(data) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .toArray();
Immutable Seq
var result = Immutable.Seq(data) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .toArray();
Native
var result = data .filter(isOdd) .map(square) .filter(lessThanThreeDigits);
