}
function every ( coll , iteratee , callback ) { return createTester ( bool => ! bool , res => ! res ) ( eachOf , coll , iteratee , callback ) }
Returns `true` if every element in `coll` satisfies an async test. If any
iteratee call returns `false`, the main `callback` is immediately called.

@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) {
callback(null, !err)
});
}, function(err, result) {
// if result is true then every file exists
});
Returns true if every element in coll satisfies an async test . If any iteratee call returns false the main callback is immediately called .
