What Is JavaScript Formatting?
The JavaScript formatter turns minified or obfuscated JS back into a clear, readable structure. It is handy for debugging third-party scripts or reading minified code. To format style code, use the CSS Formatter.
FAQ
Will beautifying JS change the code logic?
No. Beautifying only adjusts indentation, line breaks and spaces; it does not change the logic or the result.
How much can JS minification reduce the size?
It typically reduces file size by 30%–60% by removing whitespace and comments and shortening variable names. For JSON data, use a JSON formatter instead.
What is the difference between formatting and minifying JS?
Formatting expands minified code into a readable, indented form; minifying removes extra whitespace and comments and shortens names to shrink the file. They are inverse operations.
