- * Returns `true` if at least one element in the `coll` satisfies an async test.
- * If any iteratee call returns `true`, the main `callback` is immediately
- * called.
- *
- * @name some
- * @static
- * @memberOf module:Collections
- * @method
- * @alias any
- * @category Collection
- * @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 collections in parallel.
- * The iteratee should complete with a boolean `result` value.
- * Invoked with (item, callback).
- * @param {Function} [callback] - A callback which is called as soon as any
- * iteratee returns `true`, or 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
- *
- * // 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
- * // dir4 does not exist
- *
- * // 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.some(['dir1/missing.txt','dir2/missing.txt','dir3/file5.txt'], fileExists,
- * function(err, result) {
- * console.log(result);
- * // true
- * // result is true since some file in the list exists
- * }
- *);
- *
- * async.some(['dir1/missing.txt','dir2/missing.txt','dir4/missing.txt'], fileExists,
- * function(err, result) {
- * console.log(result);
- * // false
- * // result is false since none of the files exists
- * }

- *
- * // Using Promises
- * async.some(['dir1/missing.txt','dir2/missing.txt','dir3/file5.txt'], fileExists)

- * // true
- * // result is true since some file in the list exists
