While this is a plus in the development phase, it becomes a negative when it comes to serving your pages. Web servers and browsers can parse file content without comments and well-structured code, both of which create additional network traffic without providing any functional benefit. To minify...

JSON is popular with developers because it’s a flexible format for data exchange that enjoys wide support in modern programming languages and software systems. It’s text based and lightweight and has an easy-to-parse data format, meaning it requires no additional code to understand and interpr...
