Tests:

Lodash
var result = _.chain(data) .map(item => item.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);
Native
var result = data .map(x => x.counter) .filter(isOdd) .map(square) .filter(lessThanThreeDigits) ;
