every

Check if all values satisfy a test.

Similar: some, every.

function every(x, ft)
// x:  entries
// ft: test function (v, k, x)

const xlists = require('extra-lists');

var x = [['a', 'b', 'c', 'd'], [1, 2, -3, -4]];
xlists.every(x, v => v > 0);
// → false

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