You may have inferred that it is one of the most frequently used JavaScript libraries as a result, and you would be right. There are many reasons why it is widely accepted. First off, by accelerating the development process, it lowers expenses. Second, it is a popular web development option since it is easy and quick to use. Lastly, it offers effective solutions to JavaScript issues.
- Cross-browser support - Cross-browser issues are one of the biggest causes of developers' nightmares. They develop websites that are perfect on only one browser. Yet, when utilized with different browsers or versions, the identical website design parts malfunction. This issue usually occurs when websites are built entirely in JavaScript. The arrival of JQuery offers a solution to these issues. It gives you the ability to develop websites that function well across browser versions and are supported by a wide range of browsers.
- Extensible - As jQuery supports plugins, you are free to create your own or make use of third-party plugins. By doing this, you can add new functionality to your project with ease. The advantage of employing jQuery plugins is that you can save time and money that would otherwise be spent on developing those functionalities from scratch.
Disadvantages
We have already discussed a good number of jQuery's advantages. The moment has come to examine its shortcomings. The drawbacks of jQuery are listed below:
- Requires understanding of CSS - Building websites with CSS is a common practice, and jQuery requires it as well. If you want to create websites with jQuery, you should at the very least understand the basics of CSS. Other requirements include knowing how to use CSS selectors like classes and IDs. This is a significant flaw that prevents aspiring developers from using jQuery to its full potential.
- Unsuitable for complex projects - The Document Object Model (DOM) is the name of the application programming interface (API) for modifying HTML, XHTML, or XML documents (DOM). In actuality, DOM manipulation is simplified by jQuery. Sadly, you'll find that using jQuery to build complicated applications is limited by its feature set. As a result, they are inappropriate for difficult and large activities that demand additional resources.
- Debugging issues - In keeping with the previous statement, installing additional libraries and plugins will provide you access to new possibilities while developing complex apps. As more libraries and plugins are added, the size and dependencies also grow. When an issue develops, the chaos that results makes the negative effects more noticeable. Or to put it another way, debugging will be challenging due to the intricacy.
Final Thoughts
We've largely talked about jQuery's features in this blog. After the browser has displayed a page of HTML, it is simple to alter it thanks to the jQuery library. Additionally, it can create animations, connect to a server without reloading the page, and monitor visitor activity on your website.
