Major changes in jQuery 3.0 version

  •  jQuery. Deferred Promises /A+ compatible

The jQuery.Deferred objects have been updated for compatibility with Promises /A+ and ES2015 Promises that is verified with the Promises/A+ Compliance Test Suite. Legacy behaviour can be re-established by replacing any use of .then () with the now-deprecated .pipe () method.

  • Added .catch () to Deferreds

The catch () method was added to promise objects as an alias for .then (null, fn).

  • Error cases don’t silently fail

Previously, jQuery sometimes tried to make cases like this return ‘something’ instead of throwing errors. In this particular case of asking for the offset of a window, the answer up to now has been {top: 0, left: 0} with jQuery 3.0, such cases will throw errors so that crazy requests cannot be ignored.

  • Removal of deprecated event aliases

.unload, .load, and .error, deprecated since jQuery 1.8, are no more. Use .on () to register listeners.

  • Animations Now Use- request Animation Frame

On platforms that support the requestAnimationFrame API, which is practically everywhere but IE9 and Android<4.4, jQuery now use that API while performing animations.  This should result in the animations that are smoother and use less CPU time and on the mobile devices and saves battery as well.

  • Massive speedups for some jQuery custom selectors

jQuery offers some custom selectors (like: visible and: hidden) that essentially look like a CSS selector, but are resolved by jQuery selector engine. After optimizing jQuery 3, the result is now 17 times faster.

The jQuery 3.0 new Versions is now accessible with various incremental and functional changes.
