What do anonymous function do?
An anonymous function is a function that is not stored, but is associated with a variable. Anonymous functions can accept inputs and return outputs, just as standard functions do.Why are anonymous functions frequently used with event handlers? More generally, the point of using anonymous functions is that they do not require a name, because they are "event handlers" bound to a specific event on a specific object. In this case, the object is the entire Document Object Model, and the anonymous function executes when the entire DOM has loadedWhat are the two common uses of anonymous functions?
Anonymous function definition:
One common use for anonymous functions is as arguments to other functions. Another common use is as a closure, for which see also the Closures chapter. Use as an argument to other functions: setTimeout(function() { alert('hello'); }, 1000);
