_.every()

_.every(collection, [predicate=_.identity])

Checks if predicate returns truthy for all elements of collection. Iteration is stopped once predicate returns falsey. The predicate is invoked with three arguments: (value, index|key, collection).

Note: This method returns true for empty collections because everything is true of elements of empty collections.

Arguments

collection (Array|Object): The collection to iterate over.
[iteratee=_.identity] (Function): The function invoked per iteration.

Returns

(boolean): Returns true if all elements pass the predicate check, else false.
