| Format Type | Unformatted Input Sample | Beautified JS Output | Primary Use Case |
|---|---|---|---|
| Minified Single-Line JS | function hello(){console.log('world');return true;} | function hello() { console.log('world'); return true; } | Formatting production minified JavaScript scripts for debugging |
| Unindented Object & Function Literals | const user={id:1,name:'Meema',active:true}; | const user = { id: 1, name: 'Meema', active: true }; | Standardizing nested JavaScript objects and array structures |
| ES6+ Async/Await & Arrow Functions | const fetchData=async(url)=>{const res=await fetch(url);return res.json();}; | const fetchData = async (url) => { const res = await fetch(url); return res.json(); }; | Beautifying modern ES6+ async/await functions and promise chains |
| JS Comment Removal & Minification | // Developer Logger console.log('init'); /* Config load */ | console.log('init'); | Stripping developer comments and shrinking production JS bundle size |
