The Library That Tamed the Browser — Still Powering Millions of Sites
jQuery remains the most deployed JavaScript library in the world — present on over 77% of the top 10 million websites. Matlab Infotech provides expert jQuery development, maintenance, and strategic modernisation for legacy web applications that rely on jQuery's DOM manipulation, AJAX, and plugin ecosystem.

Why jQuery
Why jQuery Still Matters
Massive Installed Base
77% of the top 10 million websites use jQuery — understanding and maintaining it is a core commercial skill.
Proven Stability
jQuery 3.x LTS receives security patches — it is not abandoned, just mature. Millions of production sites depend on it.
Rich Plugin Ecosystem
DataTables, Select2, Slick Carousel, and thousands of jQuery plugins remain the easiest way to add complex UI to existing stacks.
WordPress & CMS Integration
WordPress, Joomla, and Drupal ship jQuery — most theme and plugin development still relies on it heavily.
Simple DOM Operations
For simple interactive enhancements to server-rendered HTML, jQuery's selector API is still the fastest path to a working solution.
Smooth Migration Path
jQuery is an ideal starting point for modernisation — its patterns map directly to vanilla JS and modern framework equivalents.

FAQ
Frequently Asked Questions about jQuery
Should I still use jQuery for a new project?
For new projects we recommend vanilla JS or a modern framework (React, Vue). jQuery adds a 30 KB dependency for functionality now built into the browser natively. The exception is WordPress development (where jQuery is already loaded) or when inheriting a jQuery codebase that requires consistent tooling.
Is jQuery still being maintained?
Yes. The jQuery Foundation actively maintains jQuery 3.x with security patches and compatibility updates. There is no end-of-life announced. jQuery Migrate helps upgrade from 1.x/2.x to 3.x by flagging removed APIs.
How do you approach jQuery modernisation?
We start with a dependency audit (which jQuery plugins are used and have modern equivalents), then phase the migration: replace $.ajax with fetch, .hide()/.show() with CSS classes, then finally remove jQuery itself. This happens incrementally over sprints so the site stays functional throughout.
Can you fix jQuery conflicts in WordPress?
Yes — this is very common. We resolve conflicts between theme jQuery, plugin jQuery, and WordPress's bundled jQuery by using wp_enqueue_script with noConflict mode, deferring scripts correctly, and auditing plugin loading order.
What jQuery version should I be on?
jQuery 3.7.x is the current stable version and the one that receives security updates. If you're on 1.x or 2.x, you should upgrade — use jQuery Migrate to identify breaking changes. Version 3.x also supports Promises natively, making AJAX chains much cleaner.
Is jQuery secure to use?
jQuery itself has no known critical vulnerabilities in version 3.x. Older versions (1.x, 2.x) have documented XSS vulnerabilities. The main security risk in jQuery is misuse of .html() and .append() with unsanitised user input — we audit and fix these patterns as part of our security reviews.
