Tests:

Object.keys().reduce()
for (var i=1000; i > 0; i--) { var keys = Object.keys(obj); var reduced = keys.reduce((object, key) => { object[key] = obj[key] return object; }, {}); // console.log('obj', reduced); // verify verifyPassword against newPassword via its validator function var errorMessage = obj.verifyPassword.validator(obj.verifyPassword.value, obj['newPassword'].value); // console.log('obj errorMessage', errorMessage); }
Array.map().push()
for (var i = 1000; i > 0; i--) { var newArray = []; arr.map((element) => { newArray.push(element); }); // console.log('arr', newArray); // verify newPassword (newArray[1]) via its validator function var errorMessage = newArray[1].validator('12345'); // console.log('arr errorMessage', errorMessage); }
