Checks if all values satisfy a test. 🏃 [:vhs:] 📦 🌔

Similar: some, every.

iterable.every(x, fn, [ths]);
// x:   an iterable
// fn:  test function (v, i ,x)
// ths: this argument

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

var x = [1, 2, -3, -4];
iterable.every(x, v => v > 0);
// false

iterable.every(x, v => v > -10);
// true
