8 tips to reduce unused JavaScript

Reducing JavaScript is essential for enhancing website performance by minimizing the overall size of JavaScript bundles, which can improve efficiency and loading times. The article explores various strategies to achieve this, such as code splitting, which divides JavaScript into smaller chunks that load on demand, and tree shaking, which removes unused code from the final bundle. Additionally, minifying JavaScript reduces file size by eliminating unnecessary characters, while loading scripts asynchronously prevents delays in HTML rendering. Dynamic imports and lazy loading further optimize the loading process by fetching JavaScript only when required. Keeping up with library updates and selecting lightweight, actively maintained libraries also contribute to reducing bloat. These techniques collectively help developers create faster, more efficient websites, tailored to their specific project needs.
