1.	What does hover() function do in jQuery?
Answer» If you have to call several functions that return promises and take an ACTION only when all are completed then $.when can be used. It provides a way to EXECUTE callback functions based on zero or more Thenable objects, usually DEFERRED objects that represent asynchronous events. The following is the syntax: jQuery.when(deferreds); Look at the following example: ar promises = [ $.ajax('http://google.com'), $.ajax('http://yahoo.com'), $.ajax('http://www.nytimes.com') ]; $.when.apply($, promises).then( function(result1, result2, result3){ console.log('All URLs fetched.'); } ); The ARGUMENTS passed to the thenCallbacks PROVIDE the resolved values for each of the Deferreds and matches the order the Deferreds were passed to jQuery.when().
