take

Keep first n values only.

Similar: take, drop.

function take(x, n?)
// x: an iterable
// n: number of values [1]

const ientries = require('extra-ientries');

var x = [["a", 1], ["b", 2], ["c", 3], ["d", 4]];
[...ientries.take(x, 2)];
// → [ [ "a", 1 ], [ "b", 2 ] ]

[...ientries.take(x, 3)];
// → [ [ "a", 1 ], [ "b", 2 ], [ "c", 3 ] ]
