Speed performance
Script parsing time and payload size can be reduced by minifying JavaScript files. SeoChecker shows in a table like the one below the JavaScript files of a web page that have not been minified; at the same time, it provides data on their size and on the potential savings in KiB (kibibytes) that minification would entail:
Minification is a process that aims to make code shorter: for example, unnecessary lines of code are made shorter but still valid, and whitespace is removed. Among the most widely used JavaScript compression tools is Terser, and in webpack v4 a plugin for this library is included by default to create minified build files.
