Why not to use jquery

Using jQuery can be detrimental to website performance as it adds extra weight to the page, slowing down load times. Additionally, with the advancement of modern web technologies, many features that once required jQuery can now be achieved with native JavaScript.

jQuery has long been a popular choice for developers looking to add interactivity and animations to their websites. However, in recent years, there has been a shift away from using jQuery in favor of more modern tools and technologies. In this article, we will explore some of the reasons why you may want to reconsider using jQuery in your next web development project.

One of the main reasons to avoid using jQuery is its size. jQuery is a relatively large library, with a file size of around 30KB when minified and gzipped. While this may not seem like much, it can add unnecessary bloat to your website, especially if you are only using a small portion of its functionality. This can lead to slower load times and a less optimal user experience, particularly on mobile devices with slower internet connections.

Additionally, jQuery is no longer as necessary as it once was. Many of the features that jQuery provided, such as DOM manipulation and event handling, can now be achieved with native JavaScript. This means that you can achieve the same effects without the added weight of an external library. In fact, using native JavaScript can often lead to cleaner and more efficient code, as it eliminates the need for additional layers of abstraction.

Furthermore, jQuery is not as performant as newer alternatives such as React or Vue.js. These libraries use a virtual DOM to efficiently update the user interface, leading to faster rendering times and smoother animations. In comparison, jQuery can be slower and less reliable, particularly on complex or dynamic websites.

Another reason to avoid using jQuery is that it can lead to code maintenance issues. jQuery's syntax and conventions may not be familiar to all developers, particularly those who are newer to web development. This can make it more difficult to debug and update code, especially if multiple developers are working on the same project. In contrast, using native JavaScript or a more modern framework can lead to more consistent and readable code, making it easier to maintain and extend in the future.

In addition to these technical reasons, there are also philosophical reasons to consider when deciding whether or not to use jQuery. jQuery promotes a procedural and imperative style of programming, where you manipulate the DOM directly in response to events. This can lead to spaghetti code and a lack of separation of concerns, making it harder to reason about and test your code.

On the other hand, modern frameworks like React and Vue.js promote a declarative and component-based approach, where you define the UI as a function of the application's state. This leads to more modular and reusable code, as well as clearer separation of concerns. By adopting this approach, you can build more scalable and maintainable web applications that are easier to reason about and test.

In conclusion, there are several compelling reasons to reconsider using jQuery in your next web development project. From its large file size and reduced necessity to its performance issues and code maintenance concerns, jQuery may no longer be the best choice for building modern web applications. By opting for native JavaScript or a more modern framework, you can create cleaner, more efficient code that is easier to maintain and extend in the future. So next time you reach for jQuery, think twice and consider exploring other options that may better suit your needs and goals.
