/** | |
* The opposite of [`filter`]{@link module:Collections.filter}. Removes values that pass an `async` truth test. | |
* | |
* @name reject | |
* @static | |
* @memberOf module:Collections | |
* @method | |
* @see [async.filter]{@link module:Collections.filter} | |
* @category Collection | |
* @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); | |
* }); | |
* | |
* // Using async/await | |
* async () => { | |
* try { | |
* let results = await async.reject(fileList, fileExists); | |
* console.log(results); | |
* // [ 'dir3/file6.txt' ] | |
* // results now equals an array of the non-existing files | |
* } | |
* catch (err) { | |
