Async JavaScript: A Comprehensive Review

Async JavaScript is a powerful and essential WordPress plugin for website owners. It is designed to help reduce the amount of time it takes for page load times on your website by asynchronously loading JavaScript files. This plugin is known for being one of the most efficient WordPress plugins to assist in decreasing page loading times. Async JavaScript is an open-source project created to help website owners improve their page speed and enhance users’ browsing experience on their site.

Async JavaScript: Breakdown

The main purpose of the Async JavaScript plugin is to help reduce the amount of time that it takes to load a page. The plugin works by asynchronously loading JavaScript files that are not used to initially render the page. This means that the files are loaded when the page needs them instead of loading in all of a website’s JavaScript files at once. This greatly reduces loading times by only loading the necessary files. Additionally, Async JavaScript removes any irrelevant JavaScript blocks including invalid calls, leading to a further reduction in page loading times.

The plugin is compatible with the most popular WordPress themes including Twenty Twenty, Divi, and Astra and is also compatible with the majority of the popular plugins available in the WordPress repository. Async JavaScript supports both server-side caching and user-side caching, meaning that it can adapt to multiple environments. This ensures that the plugin’s efficiency is retained regardless of the situation.

Furthermore, Async JavaScript is also feature-packed with great options such as the ability to enable or disable the plugin based on certain conditions. This is convenient as it allows website owners to control when Async JavaScript is loading, enabling or disabling under certain conditions. Additionally, Async JavaScript comes with a parsing feature which removes Script tags from the HTML source code. This is helpful for further optimization for page loading times.

Pros of Using Async JavaScript

Easy to Setup: Async JavaScript makes it simple to add custom JavaScript files to your website. You can point the plugin to your own hosted file, or point it to existing popular libraries like jQuery, Angular.js, and React.js. With the click of a button, you can add and update the code to your website without having to manually edit any of your template files.

Optimization: Async JavaScript ensures your code is loading after your page’s content. This will not only help your overall page load times but will also ensure that the code is fully optimized for performance

Debugging Tools: Async JavaScript includes a helpful set of debugging tools that can help you quickly identify potential performance or loading issues with your code. You can test the size of your code, as well as track the time it takes to load on your website.

Mobile Support: Async JavaScript is designed to save you time and work across a range of devices. The plugin provides mobile support for both WordPress and HTML5. You can also set different parameters for different device types, so you know your code is working correctly on all devices.

Compatibility: Async JavaScript is compatible with all major web browsers and devices, as well as popular frameworks like Bootstrap and Foundation. This ensures that your code is compatible with the most popular web browsers and devices.

Cons of Using Async JavaScript

Loss of JavaScript control: Though the plugin relieves some of the burden from web developers required for making asynchronous requests, it may cause them to feel a sense of helplessness as the plugin restricts some JavaScript control. The plugin can also make it harder to debug coding errors due to fewer chance of seeing the source code.

Caching problems: Using Asynchronous JavaScript can lead to issues with caching, as some users may see an old version of the file while new changes have been applied. This is because the JavaScript often fails to get cached in the browser.

Security issues: Security is a major concern with using Asynchronous JavaScript as users may be vulnerable to malicious codes and codes that reveal their personal data. This is because the script utilizes a different domain which may not be as secure as the domain itself.

Cross-platform version issues: Asynchronous JavaScript does not always work correctly across different platforms, which can result in outdated as well as no response from the web site. Furthermore, different browsers may render the same script differently.

Non-flexible behavior: The Asynchronous JavaScript plugin cannot easily be modified to fit the requirements of different websites or applications. This means that you are limited in the ways you customize the script for different needs or purposes.
