Frequently Asked Questions
JavaScript beautification is the process of formatting JavaScript code to make it more readable by adding proper indentation, line breaks, and spacing. This is especially useful when working with minified code or code that lacks consistent formatting.
The choice between tabs and spaces is often a matter of personal or team preference. Tabs are more accessible and take less storage, while spaces ensure consistent display across all editors. Most teams use either 2 or 4 spaces for JavaScript.
The tool offers four brace styles: "Collapse" keeps braces on the same line, "Expand" puts braces on new lines, "End-expand" only puts closing braces on new lines, and "None" preserves the original brace positioning.
No, beautification only changes the formatting of your code, not its functionality. It preserves all variables, functions, and logic while making the code more readable.
Yes, the tool maintains the original code structure, including comments and line breaks when the "Preserve existing line breaks" option is selected. It only modifies formatting aspects like indentation and spacing.
This tool is ideal for development and debugging purposes. For production, it's recommended to use a minifier instead, as minified code loads faster in browsers.
