Improving Java script load time on sites

Improving the loading speed of JavaScript on a website is crucial for enhancing user experience, especially on mobile devices where performance is often a concern.

Here are some strategies to make JavaScript load faster:

1. Minimize and Compress JavaScript Files
Minification: Remove unnecessary characters (like spaces, comments, and line breaks) from your JavaScript code. Tools like UglifyJS or Terser can automate this process. Run tests to determine code speed
Compression: Use Gzip or Brotli to compress your JavaScript files, reducing their size and making them quicker to download.
2. Use Asynchronous Loading
Async Attribute: Add the async attribute to your tags to download JavaScript files asynchronously, allowing the HTML parsing to continue while the script loads. Defer Attribute: Use the defer attribute to ensure scripts are executed after the HTML document has been completely parsed, preventing render-blocking. html <script src="script.js" async>

3. Load JavaScript at the End of the Body

Place your tags at the end of the <body> section. This allows the HTML content to load first, improving the perceived load time.
