every - nodef/extra-iterable GitHub Wiki

Check if all values satisfy a test.

Similar: some, every.

function every(x, ft)
// x:  an iterable
// ft: test function (v, i, x)

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

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

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