Setup

var arr = _.range(10000),
        limit = 100;
        
    var odd = function(v) { return !!(v % 2); },
        square = function(v) { return v * v; };

Test runner

var r = arr.map(square).filter(odd).slice(0, limit);

var r = _(arr).chain().map(square).filter(odd).take(limit).value();

var r = Ix.Enumerable.from(arr).map(square).filter(odd).take(limit).toArray();

var r = Lazy(arr).map(square).filter(odd).take(limit).value();

var r = lodash(arr).map(square).filter(odd).take(limit).value();

var r = Enumerable.from(arr).select(square).where(odd).take(limit).toArray();

var r = R.take(limit, R.filter(odd, R.map(square, arr)));

var r = from(arr).select(square).where(odd).take(limit).toArray();

var r = ramda.take(limit, ramda.filter(odd, ramda.map(square, arr)));

var r = F.take(limit, F.filter(odd, F.map(square, arr)));

var transform = transducers.compose(
  transducers.map(square),
  transducers.filter(odd),
  transducers.take(limit)
);

var r = transducers.seq(arr, transform);
