JavaScript Prettify Tips

Library Support

• React: Preserves JSX, hooks, and component patterns

• jQuery: Maintains $ and jQuery selectors safely

• Moment.js: Keeps date formatting and manipulation methods

• DOM APIs: Preserves querySelector, addEventListener, etc.

• Modern JS: Handles async/await, fetch, and Promises

What Gets Prettified

• Adds proper indentation and line breaks

• Formats code blocks with consistent spacing

• Organizes function declarations and statements

• Preserves string literals and library method calls

• Maintains all original JavaScript functionality

Safe Prettification

• Library method calls are preserved automatically

• Import/export statements remain intact

• React hooks and components are protected

• jQuery chaining and selectors are maintained

• Moment.js date operations are preserved

Best Practices

• Use consistent indentation throughout your project

• Choose between spaces or tabs based on team preference

• Consider line wrapping for better readability

• Add final newlines for better git diffs

• Use prettified code for development and debugging
