jQuery, a widely used JavaScript library since its release by John Resig in 2006, revolutionized web development by simplifying tasks such as DOM manipulation and browser compatibility issues. Its popularity surged due to its ease of use and powerful features, becoming a staple in web development. However, the rise of newer frameworks like React, Angular, and Vue, along with advances in browser standardization and native APIs, has led to a decline in jQuery's dominance. These modern frameworks offer component-based architecture and a declarative approach, making them more suitable for complex web applications. Despite this, jQuery remains relevant for simpler projects and legacy systems, especially those requiring compatibility with older versions of Internet Explorer. While its usage is decreasing, jQuery's impact on the development landscape remains significant, and it continues to be actively maintained.
