You Don't Need jQuery is a reference guide that documents native JavaScript equivalents for common jQuery methods and patterns.
The project addresses the question of whether jQuery remains necessary for modern web development. It demonstrates that contemporary browsers have implemented sufficient DOM and BOM APIs to handle tasks jQuery traditionally simplified—query selection, styling, DOM manipulation, event handling, and AJAX requests. The guide provides side-by-side comparisons showing how to accomplish these operations using plain JavaScript instead, with support for Internet Explorer 10 and above.
Developers should consult this guide when evaluating whether to include jQuery as a dependency in new projects or when considering removing it from existing ones. It suits projects where jQuery was added primarily for DOM convenience rather than for its broader ecosystem, particularly modern applications using React, Angular, or Vue where direct DOM manipulation is discouraged anyway. The project explicitly acknowledges that jQuery remains a valid choice for many use cases and recommends testing native alternatives thoroughly before migrating, as the implementations are not always completely equivalent across all scenarios.
The project maintains a comprehensive reference covering query selectors, CSS and styling, DOM manipulation, AJAX, events, utilities, promises, and animation. It includes translations in multiple languages, indicating sustained community engagement with the material. Development activity shows consistent maintenance of the reference content to keep examples current with evolving browser capabilities and JavaScript standards.
