The URL in consideration is linked to JavaScript files that haven't been minified or could benefit from further modification.
Why is this important?
During the development phase, JavaScript files often include spaces, verbosity in variable names, and comments which makes the code easier to understand and maintain. However, these elements become superfluous in the production environment, unnecessarily increasing the size of files being transferred over the network without enhancing functionality.
These include extra spaces, line breaks, comments, and block delimiters, all implemented for human readability rather than required execution.
By removing these irrelevant parts through minification, you can diminish file size, which translates into swifter loading times and reduced bandwidth expenditure.
What does the Optimization check?
This Optimization is activated for any internal URLs that point to JavaScript files where further minification is possible.
Examples that trigger this Optimization:
This Optimization is initiated for any JavaScript resources discovered to have superfluous content such as comments or spacing:
var array = [];for (var i = 0; i < 20; i++) { array[i] = i;}
How do you resolve this issue?
To address this issue, employ a JavaScript minifier to strip unnecessary components from your files. Plenty of web-based services are available where you can input your JavaScript, and receive a condensed version back, like the Closure Compiler.
