* @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) {
