/**
 * `Aigle.every` is similar to `Array#every`.
 * If all elements return truthly or a promise which has a truthly value as a result,
 * the result will be `true`, otherwise it will be `false`.
 * @param {Array|Object} collection
 * @param {Function|Array|Object|string} iterator
 * @return {Aigle} Returns an Aigle instance
 * @example
 * const order = [];
 * const collection = [1, 4, 2];
 * const iterator = (num, index, collection) => {
 *   return Aigle.delay(num * 10)
 *     .then(() => {
 *       order.push(num);
 *       return true;
 *     });
 * };
 * Aigle.every(collection, iterator)
 *   .then(value => {
 *     console.log(value); // true
 *     console.log(order); // [1, 2, 4];
 *   });
 *
 * @example
 * const order = [];
 * const collection = { a: 1, b: 4, c: 2 };
 * const iterator = (num, key, collection) => {
 *   return Aigle.delay(num * 10)
 *     .then(() => {
 *       order.push(num);
 *       return true;
 *     });
 * };
 * Aigle.every(collection, iterator)
 *   .then(value => {
 *     console.log(value); // true
 *     console.log(order); // [1, 2, 4];
 *   });
 *
 * @example
 * const order = [];
 * const collection = [1, 4, 2];
 * const iterator = num => {
 *   return Aigle.delay(num * 10)
 *     .then(() => {
 *       order.push(num);
 *       return n % 2;
 *     });
 * };
 * Aigle.every(collection, iterator)
 *   .then(value => {
 *     console.log(value); // false
 *     console.log(order); // [1, 2];
 *   });
 *
 * @example
 * const collection = [{
 *  uid: 1, active: false
 * }, {
 *  uid: 4, active: true
 * }, {
 *  uid: 2, active: true
 * }];
 * Aigle.every(collection, 'active')
 *   .then(value => console.log(value)); // false
 *
 * @example
 * const collection = [{
 *  uid: 1, active: false
 * }, {
 *  uid: 4, active: true
 * }, {
 *  uid: 2, active: true
 * }];
 * Aigle.every(collection, ['active', true])
 *   .then(value => console.log(value)); // false
 *
 * @example
 * const collection = [{
 *  uid: 1, active: true
 * }, {
 *  uid: 4, active: true
 * }, {
 *  uid: 2, active: true
 * }];
 * Aigle.every(collection, { active: true })
 *   .then(value => console.log(value)); // true
