Pros and Cons of jQuery

jQuery is one of the JavaScript libraries which is used to simplify the HTML traversal, DOM manipulations, animations, and events on different browsers. The tools included in the library allow implementation of the functionality and effects without needing to write the full code. The primary features of jQuery include:

  • DOM selectors to retrieve different elements like tag name, CSS class name, and attribute name;
  • DOM manipulations to add or remove elements, modify HTML or CSS class;
  • Applying special effects to DOM;
  • Library of numerous DOM events;
  • AJAX functions to load data without refreshing a page;
  • Support of multiple browsers;

Considering that jQuery is a highly effective JavaScript library, it is vital to discuss its pros and cons.

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.
  • Cross-browser compatibility includes popular browsers like Internet Explorer, Edge, Chrome, Firefox, Safari, and mobile browsers on Android and iOS. Building a page with jQuery helps to avoid the collapsing elements on other browsers, unlike developing with just JavaScript.
  • 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).

Final thoughts

All in all, one may agree that the main utility of jQuery is to make JavaScrip coding easier by using methods requiring fewer lines of code. Also, it has AJAX functions and allows DOM manipulations. Although jQuery might have some cons like limited features and library size, it is one of the most popular JavaScript libraries in the world. However, with the development of technologies, the effectiveness of jQuery became less relevant because most of its features can be performed with native JavaScript. There is a site that explains why you might not need jQuery and provides examples with the code.
