When to use JavaScript Formatter

Tidying event-handler samples
Cleaning pasted stack-overflow snippets
Standardizing indentation before sharing

Example

Input

const url="https://example.com/a//b";console.log(url)

Output

const url = "https://example.com/a//b";
console.log(url);

How to use

Paste code. Drop the JS you are actively editing.
Format. Run to normalize indentation.
Keep editing. Copy back into your editor or compiler JS pane.

Processing and limitations

Uses the Prettier Babel parser and two-space indentation. Strings and regular expressions are parsed as code rather than edited with whitespace regexes. Formatting does not execute code or check runtime errors.
