Advantages of using jQuery
- The initial advantage of jQuery is that it requires less code than Native JS and other libraries. Thus, since it has simple syntax, it is easy to use.
- JQuery has significant community support because it is an open-source library. Any development issue can be solved by addressing the forums where experienced users can help almost with everything.
- The animate method in jQuery provides the solution to using additional resources for the implementation of animations on a page. One can just animate the CSS values.
- JQuery supports an AJAX function that allows making a request and loading data without the need to reload the entire page.
- Easy to learn and use due to the detailed and comprehensive documentation.
Disadvantages of using jQuery
Even though there is an impressive list of features and advantages of jQuery, there are still some crucial remarks regarding the issues with this library. Namely, the cons of jQuery are considered to be:
- Requires knowledge of CSS to fully master the development of a site. In particular, a developer should be able to use CSS selectors freely.
- Size of a project. A JS file with all the elements supported in jQuery tends to grow over time when new features are introduced. As a result, developing a complex project would mean that file size will load slower.
- Limited functionality. Despite the features that jQuery offers, it still has limited capabilities and requires the installation of additional libraries and plugins. Moreover, as a result, it can lead to a complex debugging process because you would need to understand where the bugs are.
- Vulnerability of an open-source. As an open-source library, jQuery can be exposed to cross-site scripting attacks (XSS).
