jQuery is still relevant in several industries and scenarios, mainly because of legacy systems and cost-efficiency needs. Here are some key areas where it continues to thrive:
Enterprise legacy platforms: Many large corporations still run intranets, dashboards, or admin tools built a decade ago using jQuery. Rewriting these systems in React or Angular is costly and risky, so they maintain and extend them with jQuery.
CMS-based websites: Platforms like WordPress, Joomla, and Drupal still rely on jQuery for frontend interactions, plugins, and themes — especially in setups that haven’t transitioned to headless or modern JS stacks.
Government and public sector sites: These often prioritize stability and accessibility over adopting newer tech. jQuery remains a safe and predictable choice for maintaining consistent functionality.
E-commerce platforms: Many Magento and WooCommerce themes use jQuery for UI elements (like carousels, modals, and dynamic forms) because of its simplicity and wide plugin support.
Quick prototypes and small business sites: When speed and budget are limited, developers use jQuery for simple DOM manipulation and AJAX requests without the setup overhead of modern frameworks.
jQuery isn’t gone; it’s just matured into a maintenance and compatibility tool for systems that don’t justify a full rebuild. It remains a practical choice where reliability and backward compatibility outweigh innovation speed.
