* @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
* @param {AsyncFunction} iteratee - An async truth test to apply to each item
* in the collection in parallel.
* The iteratee must complete with a boolean result value.
* Invoked with (item, callback).
* @param {Function} [callback] - A callback which is called after all the
* `iteratee` functions have finished. Result will be either `true` or `false`
* depending on the values of the async tests. Invoked with (err, result).
* @returns {Promise} a promise, if no callback provided
* @example
*
* async.every(['file1','file2','file3'], function(filePath, callback) {
* fs.access(filePath, function(err) {
* callback(null, !err)
