iterable-pickas

Filter iterable with values of specified index(es), like _.pick().

var pickAs = require('iterable-pickas');
// pickAs(<iterable>, [index(es)], [begin=0], [end], [target=[]], [at])

var a = new Set(['Nefarious', 'Planetary', 'Meddling']);
pickAs(a);
// ['Nefarious', 'Planetary', 'Meddling']
pickAs(a, 2);
// 'Meddling'
pickAs(a, [2, 1, 0]);
// ['Meddling', 'Planetary', 'Nefarious']
pickAs(a, [2, 1, 0], 1);
// ['Meddling', 'Planetary']
pickAs(a, [2, 1, 0], 1, 2);
// [<1 empty item>, 'Planetary']
pickAs(a, [2, 1, 0], 1, 2, ['z', 'y']);
// ['z', 'x', <1 empty item>, 'Planetary']
pickAs(a, [2, 1, 0], 1, 2, ['z', 'y'], 1);
// ['z', <1 empty item>, 'Planetary']
