Examples
1. Standardizing JavaScript for a Project
Frontend Developer- Background
- A developer received a legacy JavaScript file with inconsistent indentation and missing semicolons.
- Problem
- The code is difficult to read and violates the team's style guide.
- How to Use
- Paste the code, select 'JavaScript', enable 'Use Semicolons', and set 'Indent Size' to 2.
- Example Config
-
language: javascript, indentSize: 2, semi: true, singleQuote: false - Outcome
- The code is automatically indented with 2 spaces, all missing semicolons are added, and the structure is clean and compliant.
2. Formatting JSON API Responses
Backend Engineer- Background
- An engineer needs to inspect a large, minified JSON response from an API endpoint.
- Problem
- The minified JSON is a single long line, making it impossible to read or debug.
- How to Use
- Paste the minified JSON string into the input, select 'JSON' as the language, and set the indent size to 4.
- Example Config
-
language: json, indentSize: 4 - Outcome
- The JSON is expanded into a multi-line, human-readable format with clear hierarchy.
