That’s why they’re also called dynamic arrays or vectors. Internally, a list uses an array for storage. If it becomes full,...

Difference between bind(),on(), delegate() in Jquery

bind() method: This method only attaches events to elements which exist beforehand i.e. state of initialized document before the events are attached. If the selector condition is satisfied for an event afterward, bind() will not work on that function. It also won’t work in the case if selector condition is removed from the element.<script>    $("#foo").bind("mouseenter mouseleave", function () {        $(this).toggleClass("entered");    });    $("#foo2").bind({        click: function () {            // Do something on click        },        mouseenter: function () {            // Do something on mouseenter        }    });    $("#foo").bind("click", function () {        alert($(this).text());    });</script>on()...

Use of c# “Yield” keyword ?

Yield is one of the most useful but under-used keywords in C#. The reason is that most of us don't even know about this keyword and the purpose it can serve for us.The functionality provided by Yield keyword is that when iterating a list, we can read an element of the loop, return to the calling code and go back to the loop again at the same point, from where it left the loop and continue processing...
