Defer parsing of JavaScript using the LiteSpeed cache plugin

Parsing is the process of examining and transforming a program into a form that a runtime environment, such as the JavaScript engine found in browsers, can execute. We can include two attributes for the scripts. They are Async and Defer. Both characteristics allow the browser to download JavaScript without interfering with HTML parsing.

The async function downloads the JS file while parsing the HTML. When the JS has been downloaded and is ready to be used, the async will pause the HTML parser and begin.

While HTML is being parsed, the JS file is downloaded using the defer method. The JS file is only run using the defer function once the HTML parser is finished.

We can follow the below steps to Defer the parsing of JavaScript using the LiteSpeed cache plugin:

1. Open the WP Dashboard and select Plugins >> Add New.

2. Look up Litespeed Cache in the repository of plugins.

3. Add the LiteSpeed Cache plugin and enable it.
