After minification: A single line of code
Minification speeds up webpage loading, thereby improving website experience, making both visitors and search engines happy.
Minification results in compact files, which makes it a web performance best practice. So, why not write code that is already minified?
Minification can break complicated scripts because of site-dependent variables like themes, plugins, and server environment. Also, minification must be done in conjunction with other performance tuning. On its own, it might not provide significant gains. Minification can also introduce errors that are hard to debug.
Despite these disadvantages, minification is usually worth attempting for potential performance gains. Learn how to minify CSS as well.
