JavaScript oversaw the evolution of web development. It allowed developers to build more functional and dynamic websites. JavaScript is very popular and favored developer community that over 95% of the websites are powered by it. However, JavaScript faced the challenge of inconsistent output across different browsers until jQuery was introduced to bring cross-browser compatibility to web development.
jQuery improved the use of JavaScript in web development in multiple ways, but in this article, we will be talking about how jQuery made JavaScript cross-browser compatible.

Prerequisite
To get the most out of this article, you should understand HTML, CSS, and JavaScript at the base level. If you are unfamiliar with these technologies, we recommend taking some time to familiarize yourself before proceeding.
What is cross-browser compatibility?
In web development, cross-browser compatibility refers to a website's or function's ability to function consistently across various browsers and devices. Cross-browser compatibility is when there are no changes in the result or behavior of a written script in different browsers.
In web development, some syntaxes behave differently in different browsers or that some browsers do not support, which causes our codes to behave differently in some browsers. Achieving cross-browser compatibility gives our project a consistent output across different browsers.
Challenges of JavaScript cross-browser compatibility in web development
JavaScript is the powerhouse language of the web. It is currently being used on more than 90% of all websites. JavaScript makes building functional and dynamic websites easy, which is difficult to achieve without JavaScript. With JavaScript's success and popularity, it still faces the challenge of inconsistencies across different browsers due to how browsers process, interpret, and execute code.
Some of the reasons for JavaScript inconsistencies are:
Rendering Differences: Due to how different browsers render JavaScript, it may lead to unexpected behavior, styling discrepancies, and layout issues on a website.
JavaScript API Variations: Some browsers may have different levels of support for JavaScript API features and implement them differently, requiring developers to write different codes for these browsers.
Event Handling Discrepancies: Some browsers have different ways of triggering events on JavaScript, such as clicks, hovers, or keypresses. Developers have to account for this when building websites. We have to modify event handlers for these specific websites.
Performance Variance: Optimizing performance with JavaScript can be challenging because of JavaScript inconsistencies among browsers. Code that works well in one browser may perform poorly in another.
Introduction of jQuery and its contribution to improving cross-browser compatibility in web development.
jQuery was introduced in 2007 as a JavaScript library to streamline the use of JavaScript in web development. jQuery simplifies JavaScript Dom manipulation, animations, and Ajax, and it is cross-browser compatible.
jQuery cross-browser compatibility simplifies and speeds up the production process of a website by reducing the amount of brainpower and time developers would spend thinking about writing different codes for different browsers. Without using special coding techniques to modify your code, jQuery will have consistent output across all major browsers, which makes it easier and faster to build websites.
jQuery quickly became an essential tool because developers no longer had to worry about their code being compatible across browsers; they just had to write their codes, and the jQuery API would compile them across all browsers with a consistent output.
jQuery's Universal API for Cross-Browser Compatibility
jQuery has a standard and simple JavaScript API that is uniform across various browsers. It takes away many of the challenges that developers face from various browsers. With this, you can rely on a uniform syntax to perform common tasks that work on all browsers.
Conclusion
jQuery brought cross-browser compatibility to web development. With jQuery, there is no need to write different functions for specific browsers.
Now that you understand how easily jQuery brings cross-browser compatibility to web development, consider exploring other ways jQuery can enhance the ease of using JavaScript for web development.
