jQuery is a JavaScript library for working with HTML documents, events, animations and asynchronous requests. It remains relevant to many existing websites. For a new project, compare its usefulness with native browser features and the rest of your chosen stack.
A practical example
A business website may depend on a jQuery plugin for a form or gallery. Begin by identifying the behaviour and the plugin's role. Test a replacement in isolation, including keyboard interaction and error handling. A gradual change can preserve working journeys while reducing unnecessary dependencies. Evaluate current compatibility rather than assuming an old integration is either harmless or automatically obsolete.
When jQuery still fits
| Focus | Practical approach | Check before proceeding |
|---|---|---|
| Existing site | Maintain a stable jQuery integration when it serves the product. | Audit plugins and compatibility before upgrading. |
| New feature | Compare a small native browser implementation. | Avoid adding a library for one simple DOM interaction. |
| Migration | Replace isolated behaviour incrementally with regression checks. | A full rewrite can introduce more risk than a targeted change. |
Should I remove jQuery immediately?
Not solely because it is an older library. Review the actual dependency, support requirements and user behaviour. A targeted, tested change is usually easier to evaluate than an unscoped rewrite.
