- Pick the indent, line width, quotes and semicolons.
- Copy the result or save it as a .js file.
What does the JavaScript formatter do?
- Prettier 3 formatting
- JSX
- Single or double quotes, with or without semicolons
- Line width 80, 100 or 120
- Errors with the line and column, and a hint when the code is another language
Frequently asked questions
- Is my code uploaded?
- No. The formatter runs in your browser; your code stays on your device.
- Why does it take a moment the first time?
- The formatter loads only when you use it, and only the parts your language needs. After that your browser keeps it.
