Vanilla JavaScript can improve website performance in several ways:

Key Performance Improvements with Vanilla JavaScript

1. Lightweight Codebase:

   • No External Dependencies: Vanilla JavaScript does not rely on external libraries or frameworks, which reduces the overall size of the codebase and results in faster page loads.

   • Less Overhead: Without the overhead of libraries like jQuery or React, websites can load more quickly and respond faster to user interactions.

2. Direct Execution:

   • Faster Execution: Vanilla JavaScript executes directly in the browser without the additional processing required by frameworks, leading to better performance.

   • Native Browser APIs: It leverages native browser APIs, which are optimized for performance and provide direct access to browser features.
