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).toArray();

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