Why Does JS Formatting and Minification Make Code Smaller? Principles and Risks Explained Clearly

Why does JS formatting and minification make code smaller? The answer is that the minifier removes comments, whitespace, and line breaks, and shortens local variable names, so the file size drops noticeably. Formatting does the opposite: it adds back indentation and line breaks to make the code readable. Both share the same parsing capability, but their goals are completely opposite. This article explains the principles and risks of minification, and also gives concrete usage in formatting, troubleshooting, large files, and API debugging.
