|
* @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over. |
|
* @param {Function} iteratee - An async truth test to apply to each item in |
|
* `coll`. |
|
* The should complete with a boolean value as its `result`. |
|
* Invoked with (item, callback). |
|
* @param {Function} [callback] - A callback which is called after all the |
|
* `iteratee` functions have finished. Invoked with (err, results). |
|
* @returns {Promise} a promise, if no callback is passed |
|
* @example |
|
* |
|
* // dir1 is a directory that contains file1.txt, file2.txt |
|
* // dir2 is a directory that contains file3.txt, file4.txt |
|
* // dir3 is a directory that contains file5.txt |
|
* |
|
* const fileList = ['dir1/file1.txt','dir2/file3.txt','dir3/file6.txt']; |
|
* |
|
* // asynchronous function that checks if a file exists |
|
* function fileExists(file, callback) { |
|
* fs.access(file, fs.constants.F_OK, (err) => { |
|
* callback(null, !err); |
|
* }); |
|
* } |
|
* |
|
* // Using callbacks |
|
* async.reject(fileList, fileExists, function(err, results) { |
|
* // [ 'dir3/file6.txt' ] |
|
* // results now equals an array of the non-existing files |
|
* }); |
|
* |
|
* // Using Promises |
|
* async.reject(fileList, fileExists) |
|
* .then( results => { |
|
* console.log(results); |
|
* // [ 'dir3/file6.txt' ] |
|
* // results now equals an array of the non-existing files |
|
* }).catch( err => { |
|
* console.log(err); |
