_.includes(collection, value, [fromIndex=0])
Checks if value is in collection. If collection is a string, it's checked for a substring of value, otherwise SameValueZero is used for equality comparisons. If fromIndex is negative, it's used as the offset from the end of collection.
collection (Array|Object|string) − The collection to inspect.
value (*) − The value to search for.
[fromIndex=0] (number) − The index to search from.
(boolean) − Returns true if value is found, else false.
