jQuery is a JavaScript Library.
jQuery greatly simplifies JavaScript programming.
jQuery is easy to learn.
jQuery also simplifies a lot of the complicated things from JavaScript, like AJAX calls and DOM manipulation.

Two fundamental building blocks of LINQ are the concepts of "elements" and "sequences"


Sequence



A sequence can be thought of as a list of items, with each item in the list being an element. A sequence is an instance of a class that implements the IEnumerable<T> interface.


Example for sequence


int[] fibonacci = {0, 1, 1, 2, 3, 5};

sequence could be a local sequence of in-memory objects or a remote sequence

In the case of remote data sources (for example SQL Server), these remote sequences also implement the IQueryable<T> interface    





Queries that run on local sequences are known as local queries or LINQ-to-objects queries



Return value of query can be sequence or scalar value









int[] fibonacci = { 0, 1, 1, 2, 3, 5 };
// Scalar return value
int numberOfElements = fibonacci.Count();


Console.WriteLine("Count: {0}", numberOfElements);




// Output sequence return value


IEnumerable<int> distinctNumbers = fibonacci.Distinct();


Console.WriteLine("Elements in o…
