/**
* 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) {
* console.log(err);
* }
* }
